Abstract
Substituted polyacetylenes are prepared by contacting a mixture of acetylene and a substituted acetylene with a polymerization catalyst. The substituents on the polyacetylene chains increase the distance between neighboring parallel chains and shield the chains from attack by oxygen, thereby preventing crosslinking of the chains.
