Preparation of soluble graft polymers from allyl benzoate/2,2 '-azobis(N-(2-propenyl)-2-methylpropionamide) crosslinked polymers as insoluble polymeric azo initiators

摘要

2,2'-Azobis(N-(2-propenyl)-2-methylpropionamide) (APMPA) having two carbon-carbon double bonds and an azo group was copolymerized with allyl benzoate (ABz) at 60 degreesC, providing an azo groups containing:: ABz/APMPA crosslinked polymer which may act as an insoluble polymeric azo initiator. The gelation in ABz/ APMPA (70/30 mol/mol) copolymerization was discussed in detail in order to reveal the characteristic polymerization behavior of APMPA as a novel diallyl monomer. The effectiveness of the resulting ABz/APMPA crosslinked polymer to give a soluble graft polymer through cleavage of the azo crosslinkages at an elevated temperature was then examined by polymerizing ABz at 120 degreesC.
