关键词: 聚丙烯酸[2, 5-双(对甲氧基苯甲酰氧基)苄酯], 聚甲基丙烯酸[2, 5一双(对甲氧基苯甲酰氧基)苄酯], &ldquo, 甲壳型&rdquo, 液晶高分子

Abstract: Two monomers of 2, 5-bis (4'-methoxybenzoyloxy) benzyl acrylate and 2, 5-bis (4'-methoxy- benzoyloxy)benzyl methacrylate and their corresponding polymers were successfully synthesized. The mesomorphic behavior of both polymers was examined using differential scanning calorimetry(DSC) and polarized optical microscopy(POM). It was found that both polymers are noncrystalline with a glass transition temperature of 73. 1℃ for poly-[2, 5-bis(4'-methoxybenzoyloxyben acrylate] and 120. 3℃ for poly-[2' 5-bis (4'-methoxybenzoyloxy ) benzyl methacrylate], above which liquid crystalline state is formed. The clearing temperature of the former is 178. 3℃ and that of the latter is 172. 8 ℃.

Key words: Poly-[2, 5-bis (4'-methoxybenzoyloxy) benzyl acrylate], Poly-[2, 5-bis (4'- methoxybenzoyloxy)benzyl methacrylate], Mesogen-jacketed liquid crystalline polymers
