Poly(cyanoacetylene) has been prepared by polymerization of cyanoacetylene using a variety
of late-transition-metal (Pd- and Ni-based) catalysts. The effect of reaction conditions on molecular weight
and polymer yield was explored. Significant catalyst residues remain in the polymer samples. However,
spectra are consistent with the proposed poly(cyanoacetylene) structure. Notable differences in molecular
weight, effective conjugation length, and ability to undergo thermal cyclization to a supposed aromatic
ladder polymer were observed between these polymers and those prepared using conventional anionic or
radical initiators.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
