Abstract
Some polymeric photoinitiators based on alpha-hydroxymethylbenzoin and its methyl ether are used to initiate the polymerization of methyl methacrylate in solution and the crosslinking of an epoxyacrylate formulation in thin f ilms. Zn general the polymeric photoinitiators perform better than correspo nding low molecular weight model compounds. Moreover, it is found that poly meric photoinitiators based on alpha-hydroxymethylbenzoin methyl ether perf orm better than those based on alpha-hydroxymethylbenzoin. Explanations for these observations are advanced. (C) 1998 Elsevier Science S.A. All rights reserved.
