Simple Synthesis of Poly(acetylene) Latex Particles in Aqueous Media

Abstract

The metathesis catalyst 1 allows the first living cyclopolymerization of 1,6-heptadiynes. With the chiral 4-(ethoxycarbonyl)-4-(1S,2R,5S)-(+)-menthoxycarbonyl-1,6-heptadiyne highly tactic polymers with an alternating cis–trans structure and a stereoregularity of greater than 95 % are obtained. Fixation of 1 on poly(2-oxazoline) block copolymers provides access to poly(acetylene)s under aqueous conditions by micellar catalysis.
