Abstract
1-Alkynes of even carbon numbers from 6 to 18 were polymerized by using W, Mo, and Fe catalysts to give poly(1-alkynes), a type of comb-like polymer with a rigid conjugated polyene main-chain.
n=4 to 16.
The extents of their side-chain crystallization were determined by differential scanning calorimetry and discussed in comparison with poly(1-alkene) comb-like polymers which have a fiexible polymethylene main chain. Poly(1-alkynes) showed lower extents of side-chain crystallization than poly(1-alkenes) of the same carbon numbers because of their rigid main-chain structure.
