Allyl methacrylate solution polymerization

Procedure 6-1 is an example of the solution polymerization of allyl methacrylate using benzoyl peroxide as initiator. The polymer is said to be thermoplastic. 

Allyl group containing polymers have been found to cross-link readily on e-beam exposure. Free radical solution polymerization of allyl methacrylate has been shown to result in a unique polymer with about 65% pendant allyl groups and the remainder believed to be involved in a cyclization propagation step. The exact structure of this polymer has yet to be established however, it differs significantly in physical properties from anionically prepared poly(allyl methacrylate), which has a structure with 100% pendant allyl groups. The of the former polymer is llO C, compared to the latter, which is 36 The free radically prepared polymer is very sensitive to e-beam radiation (1.5 X 10"Ccm" at lOkeV) but has poor physical properties such as adhesion, etc. Copolymerization of allyl methacrylate with glycidyl methacrylate results in copolymers with equivalent...
