螺环型膨胀单体的研究进展

Research progress of spiro expanding monomers

螺环化合物因其结构的特点可用作膨胀单体添加到树脂中减少固化后体积收缩带来的不良影响。本文主要综述了近年来国外在螺环类膨胀单体方面的研究成果,介绍了部分螺环化合物的合成和研究方法,以及螺环型膨胀单体在补牙材料和阻燃材料方面的应用。

Spiro compounds owing to its structural features can be added as expanding monomers in the resins in or- der to avoid adverse impact from volume shrinkage during curing. The research results in recent years mainly at spiro ex- panding monomers were summarized, the synthesis and research methods of part of spiro compounds and application in dental restoratives and flame retardant materials were introduced.
