The purpose of present invention provides a polymeric liquid crystal composition comprising a liquid crystal compound, which has low temperature nematic phase, excellent compatibility incorporated with other polymeric liquid crystal compounds, and obtaining transparency and mechanical intensity after polymerization. The present invention further provides the polymeric composition presented liquid crystal phase comprising the liquid crystal skeleton with more than 2 cyclic structures, and the compound (I) has the part of structure showing below formula: P1-S1-A1-D1-E1. [P1; polymeric functional group. S1; -(CH2)w-, -O(CH2)w-, -(CH2)wO-, -(CH2)wC(=O)O-, -(CH2)wOC(=O)-, -C(=O)O(CH2)w-, -OC(=O)(CH2)w- (w; 1 to 20). A1, E1; hydrocarbon ring, heterocycle. E1; the ring included in liquid crystal skeleton. D1; -C(=O)-O-(CH2)m-O-, -O(CH2)m-O-C(=O)-, -O-C(=O)-(CH2)m-O-, -O(CH2)m-C(=O)-O- (m; 1 to 15).] |
