Abstract
In this paper, the ability of two photobase generators, 2-benzyl-2-dimethylamino- 1-(4-morpholinophenyl)-butanone-1 (PBG1) and tetramethylguanidine phenylglyoxylate (PBG2), to polymerize epoxides at room temperature was investigated. The polymerization, which proceeds at room temperature, was found to be speeded up in the presence of thiols. On the basis of the results, and taking into account that both photobases are released during photochemical processes that also generate radicals, interpenetrated epoxy-acrylate polymer networks were also produced. Finally, a polythiourethane polymer was obtained using the strongest photobase generator PBG2.
