It is recommended to look at polymer chemistry. Doudou. 12 18 (conTAct ta in the station) can't say that. Each polymerization has its own characteristics. In ordinary free radical polymerization, the molecular weight should depend on the concentration of free radicals. The concentration of free radicals is large and the molecular weight is small. The concentration of free radicals is small and the molecular weight is large. That's me, 5698 (conTAct ta in the station). Of course not. . . Zhangjianl (station contact TA) was originally published by Ryan 602 on 2011-0/-060608: 27: 42: Why? Thank you very much. Read a book. 7 1429 (in-sTAtion contact ta) is related to the polymerization reaction type. If the reaction time is long, side reactions may occur, such as chain transfer, transesterification and ether exchange. But the molecular weight will decrease. Doudou. 12 18 (conTAct ta in the station) depends on the specific situation. If the reaction system you choose has side reactions after a certain period of time, Hwweven (in-station contact TA) does not consider the side reactions, and the molecular weight of chain polymerization does not change with time, but the molecular weight of step polymerization increases with time. Living polymerization is a special case, and the molecular weight increases linearly with time lzq 1985 (in-station contact with TA), which involves the difference between chain polymerization and step polymerization, as well as the difference between conversion rate and molecular weight. It is recommended to look at polymer chemistry. The molecular weight of step polymerization increased with the increase of reaction time. The longer the polymerization time, the more serious the aging, and the different properties of the prepared materials. Xisogr (in-sTAtion contact ta) is not necessary. The longer the reaction time, the higher the monomer conversion rate, but various side reactions such as chain exchange and transfer may shorten the molecular chain. Gaofenzili (in-station contact TA) is not, depending on many factors such as chain transfer agent and polymerization mode. He xiangfeng (conTAct ta in the station) has no essential relationship. Some substances are formed by degradation. The Chief Cabinet Secretary (station contact TA) is not. Different polymerization mechanisms have different effects of time on the reaction. The molecular weight of step polymerization increases with the increase of reaction time, while the reaction time of free radical polymerization has little effect on the molecular weight, only on its conversion rate.
