研究了壬酸胆甾酯与甲基丙烯酸甲酯-甲基丙烯酸丁酯无规共聚物共混体系的等温结晶动力学.讨论了共聚物组成及分子链刚性对体系中胆甾液晶组分结晶速度及成核方式的影响
The isothermal crystallization of fixtures of poly(MMA-co-BMA) with diffrent composition and cholesteryl nonanoate(ChN have been studied by differential scanning calorimetry(DSC). The Avrtal exponent n and rate constant k for ChN /Poly(MMA-co-BMA) crystallized at different temperatures were examined.It was found that the rate of nucleation and crystallization enthalpy(△HsA-K) of ChN both depend on molecular rigidity of copolymers.
