Abstract
Abstract A series of new allyl and vinyl carbonates has been prepared by the reaction of allyl and vinyl chloroformates with 4-hydroxyphenyl esters of p -substituted benzoic acid, under phase-transfer catalysis conditions. These compounds, which exhibit nematic phases, have been bound onto a polysiloxane backbone by hydrosilylation. The side-chain polymers have been examined by 1 H and 13 C n.m.r. spectroscopy, g.p.c., differential scanning calorimetry and optical polarizing microscopy.
