The two-step copolymerization of diethylene glycol bis(allyl carbonate) (CR-39) with methacrylic ester of fluorine containing alcohol (FMA), i.e., trifluoroethyl methacrylate (3FMA) and 1,1,3-trihydroperfluoropro-pyl methacrylate (4FMA), was carried out to prepare a light-focusing plastic rod. The relations between the preparation conditions and the optical characteristics of the resulting rods were considered in the following terms: (a) diffusibilities of CR-39 and FMA; (b) copolymerization of FMA with CR-39; (c) slower diffusion rate of 4FMA than that of 3FMA due to molecular size effect. Low chromatic aberration and the excellent imaging property of the CR-39-3FMA rod lens are also presented.
进行了二甘醇双（烯丙基碳酸酯）（CR - 39）与含氟醇的甲基丙烯酸酯（FMA），即甲基丙烯酸三氟乙酯（3FMA）和甲基丙烯酸1,1,3 - 三氢全氟丙酯（4FMA）的两步共聚反应，以制备光聚焦塑料棒。从以下几个方面考虑了制备条件与所得棒材光学特性之间的关系：（a）CR - 39和FMA的扩散率；（b）FMA与CR - 39的共聚反应；（c）由于分子尺寸效应，4FMA的扩散速率比3FMA慢。还介绍了CR - 39 - 3FMA棒透镜的低色差和出色的成像性能。
