Synthesis of homo-and copolymers of paradiethynylbenzene in the presence of the cobalt carbonyl-diphenylbutadiyne com

摘要

Homopolymerization of para-diethynylbenzene and its copolymerization with 1,4-diphenylbutadiyne(DPDA)in a boiling solution using carbonyl cobalt-DPDA complex as a catalyst leads to the formation of weakly branched polymers with high thermal-oxidative stability.
