SOME ASPECTS REGARDING RING-OPENING COPOLYMERIZATION OF CYCLOOLEFINES

Ring-opening copolymerization of cyclopentene, cyclooctene, cyclooctad iene and cyclododecene in all possible alternatives was investigated i n order to get additional information on cycloolefines reactivity agai nst the same comonomer, as well as the determination of the modality i n which reciprocal presence of cycloolefines influences the kinetics o f the copolymerization process and the copolymers composition. The exp eriments led to the conclusion that the cyclooctene reactivity in copo lymerization reactions is higher than in a homopolymerization process. The reactivity ratios certify a high reactivity for cyclopentene and cyclooctadiene regardless of the copolymerization system.
