Acceleration of the UV Curing of Oxetane Monomers
New processes are proposed for preparation of novel, highly reactive, renewable substrate oxetane polymers, making it possible to use cationic oxetane photopolymerizations in many high-speed coatings, printing inks, adhesives, as well as in additive manufacturing processes such as stereolithography, digital imaging and in ink-jet printing. Specifically, an epoxide accelerant, such as 2,2-substituted epoxide, 2,2,3-substituted epoxide, 2,2,3,3-substituted epoxide, and mixtures thereof, is reacted with one or more equivalents of a 3-monosubstituted oxetane or a 3,3-disubstituted oxetane.
