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.
以下为发明的可聚合脂环族酯的化学式(1)或(2):
其中,环A、环B、环C、环D和环E中的每一个都是非芳香碳环,R是可聚合的不饱和基团,而Ra1、Rb1和Rc1中的每一个,可以相同也可以不同,是氢原子、羟基(可以通过保护基团来保护)或RCO2基团,其中R的含义与上述定义相同。环A、环B、环C、环D和环E中的每一个,例如可以是环戊烷环、环己烷环或桥环。R包括例如乙烯基、异丙烯基或芳基。
