KINETIC AND APPLIED STUDY OF UV LIGHT PHOTOSENSITIVEINITIATING POLYMERIZATION OF METHYLMETHACRYLATEBY BIIMIDAZOLE PHOTOSENSITIVE SYSTEM

doi:10.7517/j.issn.1674-0475.1999.03.247

Abstract

Abstract: The ultraviolet photosensitive initiating system is composed of 4,4’-bis(N,N’-dimethylamino) benzophenone (MK), 2-chlorohexaarylbiimidazole (o-Cl-HABI) and a hydrogen donor coinitiator ndodecyl mercaptan (SH). Under the irradiation by high pressure mercury lamp, the relationship between the photopolymerization rate of MMA and the concentration of each component of the system, including MK, o-Cl-HABI, SH and MMA, was studied. The excellent results have been obtained through studying the system’s application on PS printing plate.

Key words: biimidazole, photopolymerization, photosensitive initiating system
