SYNTHESIS AND CHARACTERIZATION OF LIQUID CRYSTALLINE POLYSILOXANE WITH (p-((4-ALLYLOXY)BENZOXY)BENZOXY)-4- METHOXYPHENYL AS A MONOMER

侧链型液晶聚合物是目前很有兴趣的研究课题之一。

A liquid crystalline polysiloxane has been prepared by a hydrosilation reaction of poly (methylhydrosiloxane) with (p-((4-allyloxy)benzoxy)benzoxy)-4-methoxyphenyl. The chemical structure of the monomer and polymer was confirmed by IR and 1H-NMR analysis, and as many as 13% α-addition isomeric side chains were found from the NMR spectrum of the polymer. In addition ,the phase behavior of the monomer and polymer were studied by optical polarized microscopy and DSC measurements.
