An optical material formed of a copolymer is disclosed. The copolymer is obtained by polymerizing a monomer composition composed of a particular N-substituted trifunctional monomer having a triazine ring structure and a monomer copolymerizable with the isocyanurate. Where the copolymerizable monomer is a specific aliphatic bifunctional monomer, the monomer composition additionally contains a further monomer which is copolymerizable with the aforementioned components and contains at least one ethylenically-unsaturated group.
本发明公开了一种由共聚物构成的光学材料。这种共聚物是通过聚合由具有
三嗪环结构的特定 N 取代三官能团单体和可与异
氰脲酸酯共聚的单体组成的单体组合物而得到的。在可共聚单体为特定脂肪族双官能团单体的情况下,单体组合物还含有另一种单体,该单体可与上述组分共聚,并含有至少一个
乙烯不饱和基团。
