Abstract

Homopolymerization of p-[tris(trimethylsilyl)silyl]phenylacetylene [p(Me₃Si)₃SiPA] by Rh catalyst provided insoluble polymer. On the other hand, copolymerization of p(Me₃Si)₃SiPA with p-(trimethylsilyl)phenylacetylene (pMe₃SiPA) at 80:20, 50:50, and 20:80 feed ratios afforded high molecular weight copolymers (M(w) > 1x10⁶), all of which were soluble in common solvents such as toluene and chloroform. The mole ratios of p(Me₃Si)₃SiPA to pMe₃SiPA unit in copolymers were close to those in the feeds. The oxygen permeability increased monotonously with increasing p(Me₃Si)₃SiPA content of copolymer in correspondence with fractional free volume; the value of the copolymer for the 80:20 feed ratio reached 770 barrers.
