Abstract

二甘醇双烯丙基碳酸酯的聚合方法，该方法可有利地用于生产低折射指数的塑料透镜，该方法包括在作为催化剂的二异丙基过氧化二碳酸酯的存在下对二甘醇双烯丙基碳酸酯进行伽马辐射的步骤。

Description

二甘醇双烯丙基碳酸酯的聚合方法 
发明领域
本发明涉二甘醇双烯丙基碳酸酯的聚合方法。该聚合的碳酸酯可用于低折射指数的透镜。
发明背景
塑料眼科透镜根据它们的折射指数分类，且折射指数限定了透镜的度数。
迄今，低折射指数(1.52)的透镜通常由二甘醇双烯丙基碳酸酯的热聚合制成。这个方法在于使二甘醇双烯丙基碳酸酯在热引发剂(通常包含二异丙基过氧化二碳酸酯)存在下进行热聚合。这样的热聚合由不同温度下的热循环组成。
与这个已知方法相关的缺点是高能量消耗和时间耗费。
发明目的
本发明的一个目的是提供改进的二甘醇双烯丙基碳酸酯的聚合方法，该方法可有利地用于低折射指数眼科透镜的生产。
本发明的另一个目的是提供二甘醇双烯丙基碳酸酯的聚合方法，该方法可避免与已知方法相关的高能量消耗。
本发明的又一个目的是提供二甘醇双烯丙基碳酸酯的聚合方法，该方法可有利地用于具有优良光学性能的眼科透镜的生产。
本发明的再一个目的是提供二甘醇双烯丙基碳酸酯的有效的聚合方法。
发明内容
根据本发明，提供了二甘醇双烯丙基碳酸酯的聚合方法，该方法可有利地用于生产低折射指数的塑料透镜，该方法包括对二甘醇双烯丙基碳酸酯在作为催化剂的二异丙基过氧化二碳酸酯存在下进行伽马辐射的步骤。
根据本发明，聚合的方法包括与已知的热聚合方法相区别的伽马辐射步骤。具体而言，本发明使二甘醇双烯丙基碳酸酯在所述的催化剂存在下在75-85KGy的辐射剂量下进行伽马辐射步骤8-10小时。如果剂量增加到高于85KGy，则透镜具有微黄的颜色。然而，如果剂量低于75KGy，聚合是不完全的。
优选地，在所述的聚合步骤中使用1-1.5％的催化剂。
在随后的实施例中，其它的目的和优点将显而易见。
实施例1
取二甘醇双烯丙基碳酸酯(也被称作CR-39)并与1.2％的二异丙基过氧化二碳酸酯(也被称作IPP)相混合。将混合物吸入注射器并注入配有衬垫的玻璃毛坯中。含有聚合混合物的模具暴露在15-85KGy的伽马辐射下。
玻璃毛坯暴露在伽马辐射下变暗(turned dark)，得到折射指数为1.52的、透过率高于90％和Barcol硬度为40的无色的、清洁的和透明的透镜。
