Industrialization of Highly Efficient Photoinitiators TPO and a series of products

摘要

Intruduction 　　In UV curing technology, photoinitiators are very important materials. When photoinitiatorsare radiated, they generate radicals, which initiate monomer and prepolymer to occur radical polymerization. This reaction makes liquid-stage coat into solid-stage one, forming cross-link polymer with steric network structure. 　　In 1999-2000, our company had developed a series of photoinitiators, such as 2hydroxy-2-methyl-l-phenylpropanone(IHT-Pl1 173), 1-hydroxycyclohexyl phenyl ketone(IHT-PI 184), 2,4.6-Trimethylbenzoyl diphenylphosphine oxide(IHT-PITPO) and 2-methyl-1-[4-(methylthio)-phenyl]-2-morpholinopropan-l-one(IHT-PI907).……
