Major achievements
achievements in scientific research
In biomedical polymers, Feng Xinde focused on anticoagulant materials and drug controlled release systems, as well as the initial reaction mechanism of polymer aging and biological aging.
According to the characteristics that polymer science is both a basic science and an applied science, Feng Xinde demanded that polymer synthesis should be closely combined with the study of structure and properties. Starting from the development of petrochemical industry, he advocates that scientific and technological talents enter scientific research units in petrochemical departments, which is conducive to the digestion, absorption and innovation of imported technologies. Advocating pragmatism and innovation in scientific research. For example, during the school-run chemical plant in the 1970s, he thought that in addition to organizing the production of dental self-setting resin, anaerobic adhesive and other related products to optimize the formula, he should also develop a system that can be triggered quickly, and study its triggering mechanism and the role of the stabilizer of anaerobic adhesive. , make scientific research and production practice closely linked. He argues that scientific research can only have vitality if it is constantly innovated. For a long time, I have mainly studied the basic theory of polymer chemistry and achieved innovative results in the following aspects. In the aspect of vinyl radical polymerization, the content involves redox initiation system and reaction mechanism. In the system initiated by peroxide and amine, it is proved that two kinds of free radicals generated by the reaction of peroxide and amine components can initiate monomer polymerization. The initiation mechanism of organic hydroperoxide and amine system was put forward for the first time, and it was confirmed by experiments, vinyl graft polymerization and reaction mechanism. The difficulty lies in finding out the grafting site and grafting mechanism. Using the reaction of model compounds, the grafting point of polyether urethane and polyether polyester was found out, and the grafting mechanism was put forward. Unconjugated dienes can be polymerized by free radicals and negative ions, and both of them can obtain cyclized polymers; There is little research on charge transfer photoinitiated polymerization of electron-withdrawing vinyl monomers. Through the study of photoinitiated polymerization containing amines and other electron donors, aromatic amines were extended from tertiary amines to primary and secondary amines for the first time, and it was confirmed that photoinitiated polymerization could be initiated by CTC or local excitation. In ion polymerization, there are ring-opening polymerization, * * polymerization and tetrahydrofuran-based reaction mechanism, as well as block * * * polymerization. It is found for the first time that tetrahydrofuran polymerization initiated by diacyl chloride (decanoyl chloride or hexanoyl chloride)/silver perchlorate system is living polymerization, and the center of active chain changes from positive ion to negative ion olefin polymerization, thus obtaining polymethyl methacrylate-polytetrahydrofuran-polymethyl methacrylate triblock polymer.
Since 1970s, people began to study functional polymers, especially photosensitive polymers and biomedical polymers, including anticoagulant polymers, polymer drugs and drug sustained-release systems in polymer biomaterials. The synthesis methods of these materials were studied. Through molecular design, block polymers with different structures can be synthesized to adjust the degradation and release rate of drugs, so that drugs can be released at a constant rate. In recent years, the chemical mechanism of biological aging has been studied.

Feng Xinde has successively completed projects such as China Academy of Sciences Fund, National Natural Science Fund, Doctoral Program Fund of State Education Commission and Family Planning Commission Fund of Ministry of Health.
Feng Xinde has won six national awards.
personnel training
Feng Xinde believes that teaching and scientific research are important, but the most fundamental thing is to produce talents. In teaching, Feng Xinde attaches great importance to basic theory and experimental skills, and requires close integration of theory and practice. His lectures were lively, rich in content and distinctive in views, which won the praise of students. This is inseparable from his extensive knowledge and careful preparation of lessons. He often compares a teacher to a gardener. If you water the flowers with one load of water, you should put more than ten loads of water in the jar, often carry water and prepare lessons carefully.
In order to cultivate the scientific research ability of undergraduates, he has always attached importance to the training of graduation thesis and never stopped. 1in the autumn of 979, Professor P.J. Flory, a Nobel Prize winner who accompanied him to visit our school, introduced that undergraduates were doing graduation thesis, which aroused Florey's great interest and proposed to go to the laboratory to watch students' thesis experiments, because not all college students in the United States did graduation thesis.
In order to cultivate high-level talents, he adopted advanced methods and experiences at home and abroad and implemented unique teaching methods in combination with national conditions. Deal with several relations in postgraduate training, such as basic theory and scientific frontier, class and self-study, the cultivation of learning ability and practical work ability, and "management" and "release" and so on. He personally presided over the lecture on polymer progress, taught graduate students "polymer progress and prospect in the 1980s" and "polymer progress-living polymerization", and invited foreign experts to give academic reports, which enriched the teaching content and enabled students to keep abreast of the progress of related disciplines, understand the frontier of disciplines and master the latest information. A group of senior talents with rigorous scholarship, active academic thinking and good style of study have been trained. Two doctoral students have successively won the chinese chemical society Youth Chemistry Prize. In recognition of his achievements in cultivating talents, chinese chemical society awarded him the Yucai Award on 1989.
In order to exchange experiences and improve teaching quality, Feng Xinde also gave lectures, made academic reports or served as a professor and consultant in brother colleges and research departments. Lectures on the characteristics and development of polymers in the 1980s, the importance of polymer chemistry and physics experiments and the training of talents were given at the national symposium on polymer chemistry and physics in colleges and universities (Guangzhou, 1982) and the national experimental research class on polymer chemistry and physics (Beijing, 1984). 65438-0990 taught in Chengdu, Wuhan, Qingdao and other places, introducing the latest progress of polymerization and the development of polymer biomaterials. Feng Xinde attaches great importance to the popularization of polymer science. He used to be the editorial board of Chemistry Volume of Encyclopedia of China and the deputy editor of Polymer Chemistry, and participated in the drafting of the project framework. In addition to writing in person, he also organized writers to examine and approve matters related to aggregation.
1949 Feng Xinde taught polymer chemistry-polymerization for the first time in Tsinghua University. After the adjustment of 1952 department, he went to Peking University to teach polymer chemistry, guide graduate students' papers and prepare polymer chemistry experiments.
1953, Feng Xinde recruits graduate students in polymer chemistry, 1955 trains the first batch of polymer graduates. Since 1978 resumed postgraduate enrollment, more than 40 postgraduate students have been trained.
At the initiative of Feng Xinde, 1958 established the first teaching and research section of polymer chemistry in Peking University. Since then, he has served as the director of the teaching and research section until 1986.
