The invented polymerizable alicyclic esters are shown by the following formula (1) or (2):
wherein each of ring A, ring B, ring C, ring D, and ring E is a non-aromatic carbon ring, R is a polymerizable unsaturated group, and each of Ra1, Rb1 and Rc1 is, identical to or different from one another, a hydrogen atom, a hydroxyl group which may be protected by a protective group, or an RCO2 group, where R has the same meaning as defined above. Each of the ring A, ring B, ring C, ring D, and ring E is, for example, a cyclopentane ring, a cyclohexane ring, or a bridged ring. R includes, for example, a vinyl group, an isopropenyl group, or an aryl group.
本发明的可聚合脂环族酯由下式(1)或(2)表示:
其中环 A、环 B、环 C、环 D 和环 E 各为非芳香族碳环,R 为可聚合的不饱和基团,Ra1、Rb1 和 Rc1 各为相同或不同的氢原子、可被保护基团保护的羟基或 RCO2 基团,其中 R 的含义与上述定义相同。例如,每个环 A、环 B、环 C、环 D 和环 E 都是环戊烷环、环己烷环或桥环。R 包括乙烯基、异丙烯基或芳基等。
