Abstract:
以4，4’-二胺基二环己基甲烷、十二碳二酸、己二酸己二胺盐为反应单体制备了（亚氨基-1，4-亚环己基亚甲基-1，4-亚环己基亚氨基十二碳二酰）-co-（亚氨基亚己基亚氨基己二酰）共聚物材料（PACM12-PA66），并研究了其光学性能和力学性能.光学性能研究表明，当PACM12含量高于40%时，为可见光（400~800nm）透光度良好的高分子材料，其透光度与纯PAPACM12材料相当；共聚物材料的折光指数随PACM12含量的降低而略微增加.XRD结果分析表明，随PACM12含量的降低共聚物材料的晶粒尺寸变大，这是透光度降低的原因.力学性能研究表明，共聚物材料拉伸强度和冲击强度随PACM12含量的降低而增加.当PACM12含量为40%时，共聚物材料拉伸强度值（64.28MPa）和冲击强度值（14kJ/m2）分别比纯PACM12材料提高了16%和33%.
