Radical polymerization of N-(4-butoxycarbonylphenyl)maleimide,its co-polymerization with methyl methacrylate,styrene and acrylonitrile,and the properties of the resulting polymers

摘要

Co-polymers were synthesized from free radical co-polymerization of methyl methacrylate (MMA),styrene (ST) and acrylonitrile (AN) with N-(4-butoxycarbonylphenyl)maleimide (BCPM),using benzyl peroxide (BPO) as an initiator and DMF as a solvent at 85°C.A series of co-polymers of MMA,ST and AN with BCPM was prepared using different feed ratio of co-monomers.The thermo-stabilities and physical properties of the polymer samples obtained have been described.The values of monomer reactivity ratios r1 and r2 determined by Fineman-Ross and Kelen-Tudos methods are 0.28 and 0.90 in BCPM/MMA,0.20 and 0.39 in BCPM/ST and 0.51 and 1.23 in BCPM/AN systems.Alfrey-Price Q and e values for BCPM are Q = 1.39 and e = 1.57 in BCPM/MMA,Q = 2.53 and e = 2.15 in BCPM/ST and Q = 1.11 and e = 1.89 in BCPM/AN systems.
