Disclosed is a triazine ring-containing hyperbranched polymer containing a repeating unit structure represented by the expression (1). By this means, it is possible to achieve a triazine ring-containing polymer which, alone, has high heat resistance, high transparency, high refractive index, high light resistance, high solubility, low volume shrinkage without adding metal oxides; and also a membrane-forming composition containing the same.
(In the formula, R and R' represent independently a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or an aralkyl group, and A represents an alkylene group optionally having a branched or alicyclic structure of 1 to 20 carbon atoms.)
本发明公开了一种含
三嗪环的超支化聚合物,该聚合物含有表达式(1)所代表的重复单元结构。通过这种方法,可以在不添加金属氧化物的情况下,获得一种单独具有高耐热性、高透明度、高折射率、高耐光性、高溶解性、低体积收缩性的含
三嗪环聚合物,以及含有这种聚合物的成膜组合物。
(式中,R 和 R' 分别独立地代表氢原子、烷基、烷氧基、芳基或芳烷基,A 代表可选具有 1 至 20 个碳原子的支链或脂环结构的亚烷基)。
