Synthesis of new disiloxane-containing polymers

Abstract

Synthesis of new disiloxane-containing polymers is described. New oxygen permeable membrane polymers and side-chain liquid crystalline polymers were synthesized by taking advantage of low rotational barrier energy around silicon-oxygen bond. Stereoregular poly[(methylphenylsilylene)trimethylene] and optically active poly[{(1S)-1-(1-naphthyl)-1-phenyl-3, 3-dimethyldisiloxan-1, 3-diyl}ethylene] were synthesized for the first time starting from optically active allylhydrosilane and optically active 1-vinyl-3-hydrodisiloxane, respectively.
