Abstract

The copolymerization of maleic anhydride(MAn) with phenyl-4'-vinylp henylbutadiyne(PVPB) was carried out using 2,2'-azobisisobu tyronitrile as an initiator. Although PVPB does not homopolymerize by free radicals in solution, it copolymerized giving copolymers having average molecular weights up to 12,000, and consisting of slightly more PVPB units. The monomer reactivity ratios were estimated to be r(MAn)=0 and r(PVPB) =0.1 - 0.2. It was concluded that the copolymerization likely proceeds via a free monomer propagation mechanism rather than through a donor-acceptor complex mechanism.
