This invention describes the preparation of some new Mannich polymers and copolymers and teaches their general use as photosensitizers for onium salts for use in the initiation of free radical polymerization of vinyl monomers. These Mannich polymers are unexpectedly more efficient as photosensitizers than are the non-polymeric photosensitizers.
本发明描述了一些新型曼尼希聚合物和共聚物的制备方法,并教授了它们作为鎓盐光敏剂的一般用途,用于引发
乙烯基单体的自由基聚合。这些曼尼希聚合物作为光敏剂的效率出乎意料地高于非聚合物光敏剂。
