| 摘 要： | 采用负离子聚合技术，在单体质量浓度为0．20—0．25g／mL，聚合温度为65—80℃时，通过四步聚合反应合成了一种具有较好光学性能的丁苯聚合物，探讨了四氧呋喃（THF）／正丁基锂（简称Li）及混合单体进料时间对产物光学性能的影响。结果表明，当THF／Li（摩尔比）为6，进料时间为60min时，产物光学性能最佳，雾度可降低至6％。

| Abstract: | The mechanism and the kinetics of the synthesis of styrene-butadiene copolymers have been deeply investigated, and some important conclusions have been summarized in related reports and literatures [1, 2]. In this article, a new styrene-butadiene copolymer with excellent optic properties initiated by n-BuLi (represented as Li following) in cyclohexane was synthesized, which comprised a polystyrene homogeneous segment, a poly(styrene-butadiene) random segment and a small homogeneous polybutadiene segment, and the effect of the mole ratio of THF/Li and the injecting time of the monomer mixture which formed the poly(styrene-butadiene) random segment were investigated by the orthogonal tests based on the two main factors to reduce the haze of the copolymer. |
