Abstract
Acetylene-containing polymers, obtained by the radical polymerization of aliphatic enynes, were subjected to the thermal crosslinking reaction on the basis of the reactivity of the acetylene moieties. Thermal properties of the resulting crosslinked polymers were dependent upon the character of the substituents, being also correlated to the thermal decomposition temperatures of polyenynes. Namely, the polymers having sterically less hindered substituents have higher decomposition temperature than those having hindered substituents as a result of efficient crosslinking process.
