| Abstract: | Side chain liquid crystalline golysiloxanes conta ing biphenyl and benzyl ether mesogen were synthesized by the hydrosilation of poly（methylhydrcsiloxane） with 4-（4-allyloxybenzytoxy）-4'- methoxybiphenyl（M1）,4-（4-allyloxybenzyloxy）-4'-ethoxybiphenyl（M2）,4-（4-allyloxybenzyloxy）-4'- propoxybiphenyl（M3）,4-（4-allyloxybenzyloxy）-4'-butoxybiphenyl（M4）,4-（4-allyloxybenzyloxy）-4'- pentyloxybiphenyl（M5）.The phase behavior of monomeric and polymeric liquid crystals was chararcterized by differential scanning calorimetry and optical polarization microscopy.Both the monomeric and polymeric liquid crystals exhibit liquid crystal behaviors. |
