Organic glasses and surface coatings are prepared, with short hardening cycles, by submitting to the action of U.V. light a liquid polymerizable composition containing at least one di-(allyl carbonate) or poly-(allyl carbonate) of a diol or polyol, a photoinitiator and a vinyl ester monomer and/or an organic peroxide.
The composition can additionally contain small amounts of an organic compound selected from among those compounds which are used in the art in order to stabilize the organic polymers to the degrading action of U.V. light.
The composition is preferably heated before being treated with U.V. iight.
将含有至少一种二元醇或多元醇的二碳酸(烯丙基)酯或多碳酸(烯丙基)酯、光引发剂和乙烯基酯单体和/或有机过氧化物的液态可聚合组合物置于紫外光下,可制备出硬化周期短的有机玻璃和表面涂层。
此外,该组合物还可以含有少量的有机化合物,这些化合物可以从本领域常用的化合物中选出,以稳定有机聚合物,使其不受紫外光的降解作用影响。
在用紫外光处理之前,最好对组合物进行加热。
