| 摘 要： | 研究了手性丙烯酸酯侧链液晶聚合物聚４ 丙烯酰十一烷氧基 ４′ ［Ｓ（ ） ２ 甲基丁氧基］ 联苯（ＰＡ １１）的分子量对其液晶行为的影响，结果表明，ＰＡ １１的相变温度随聚合度增大而升高，当聚合度大于１５以后，分子量对相变温度影响不明显，低聚合度的ＰＡ １１只表现出双向性的ＳＡ相，而聚合度大于７的ＰＡ １１不仅具有双向性ＳＡ相，而且还表现出双向性ＳＣ相；分子量分布对ＰＡ １１的液晶相转变也有影响 |

| Abstract: | The molar mass effect on phase transition of a chiral side chain liquid crystal poly 4 acryloxyloxy undecanoloxy 4′ [ s( ) 2 methylbutyloxyloxy] biphenyl (PA 11) was studied in the present work. The experimental results show that the mesomorphic temperature range depended on the degree of polymerization ( DP ) of polymer. The PA 11 with DP below 7 exhibits an enantiotropic S A mesophase, while polymer with DP over 7 displays both S A and S * C enantiotropic mesophases. Moreover, molar mass distribution has an effect on liquid crystalline behaviour of polymer. |
