膨胀型UV单体的研究是由的,比如下面是一篇膨胀型螺环UV单体的文章摘要,发表在2008年的欧洲聚合物杂志上。 我希望生产单体公司把各种膨胀性的UV单体做好,在市场上销售,我们在我们的配方中用一定比例的量,来大大降低UV树脂的收缩率。

Abstract
The synthesis of an epoxy functionalized spiroorthocarbonate (SOC) is reported. The obtained monomer has been used a slow shrinkable additive in cationic UV curing of a commercially available dicycloepoxy resin. A polymer network flexibilization was evidenced by increasing the SOC content in the photocurable formulation. It has been demonstrated that SOC acts as shrinkage reduction additive reaching expansion on volume after polymerization in the presence of 10 wt% of the functionalized spiroorthocarbonate.
