Precise Isomerization Polymerization of Alkenylcyclohexanes: Stereoregular Polymers Containing Six-Membered Rings along the Polymer Chain

摘要

Pd and Ni diimine complexes catalyze the isomerization polymerization of alkenylcyclohexanes to afford polymers composed of alternating frans-cyclohexane-l,4-diyl rings and oligomethylene spacers with high selectivity. The melting points of the polymers vary from 130 to 226 ℃ depending on length of the oligomethylene spacer.
