ABSTRACT:
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.
