Synthesis and characterization of side chain liquid crystalline polysiloxanes containing benzyl ether linking units

摘要

Side chain liquid crystalline polysiloxanes containing benzyl ether linking units were synthesized by the hydrosilylation of poly (methylhydrosiloxane) with a series of 4-(4-alkoxybenzyloxy)-4'-allyloxybiphenyl monomers[4-(4-propoxybenzyloxy)-4'-allylolxy biphenyl (M_1), 4-(4-ethoxybenzyloxy)-4'-allyloxybiphenyl (M_2), 4-(4-propoxybenzyloxty)- 4'-allyloxybiphenyl (M_3), 4-(4-butoxybenzyloxy)-4'-allyloxybiphenyl (M_4), 4-(4-pentoxy- benzyloxy)-4'-allyloxybiphenyl (M_5), 4-benzyloxy-4'-allyloxybiphenyl (M_6)].
