Methacrylate was grafted onto polypropylene fiber by reverse atom transfer radical polymerization initiated by peroxide.
The radiation polymer in the monomer is heated to initiate polymerization, which belongs to the category of grafting. However, due to the loss of mechanical properties caused by side reactions such as combination, disproportionation, crosslinking and chain breakage, it is difficult to obtain a clear molecular weight of the grafted polymer.
Heating and irradiation of polymers on monomolecular objects initiate polymerization, which is included in the classification of grafting. However, it is difficult for molecular grafted fibers to obtain a certain molecular weight, because chemical side reactions such as combination, disproportionation, crosslinking and chain breakage lead to the loss of mechanical properties.
