摘要: 本文详细研究了以甲基丙烯酸甲脂为主链,带有胆甾侧链的梳型聚合物(PCHPM)的光学性质及螺旋结构。在一定条件下,侧链上的胆甾基团可自由取向,形成胆甾型液晶。通过比旋光率、红外圆二向色性吸收及大角光散射的研究,给出了PCHPM的螺旋结构的螺距尺寸及其与共聚物组成的关系。

Abstract: This paper presents a detail study on the structure and switching properties of liquid crystalline copolymers of cholesteric ester of 1,2-hydroxypropyl 2,4-diisocyanatoluene methylmethacrylate (PCHPM). Under certain conditions PCHPM was observed turning into liquid crystalline state by crossed polarizers.The optical properties of the copolymers were determined by specific rotation, circular dichroism and wide-angle light Scattering Weas rements,
