Abstract

Two kinds of benzophenone (BP) derivatives, dodecyl-benzophenone (BP-D) and hexadecoxyl-benzophenone (BP-H), used as new photoinitiators have been synthesized by Friedel-Crafts reactions and identified by ultraviolet (UV) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. The kinetic characteristics of photoinitiating crosslinking of BP-D and BP-H comparing with BP in the photocrosslinking of polyethylene (PE) in the melt and their compatibility with PE resin have been examined by gelcontent measurement and thermal migration experiments. The results show that these two BP derivatives are excellent photoinitiators, which have better compatibility, less volatility, higher photoinitiating efficiencies. and longer storage time than BP itself. These two new photoinitiators are promising for industrial applications of the photocrosslinking of polyolefins and curing of coats.
