Abstract:
     The present invention discloses polymer type diphenyl ketone light initiator as shown and its preparation process. The preparation process includes reaction between halogenated diphenyl ketone and p-aminophenol or p-amino thiophenol to produce diphenyl ketone with amino group, introducing maleimide group via the amino group, the free radical polymerization of diphenyl ketone with maleimide group and tertiary amine with unsaturated double bond to obtain the polymer type diphenyl ketone light initiator with tertiary amine structure as hydrogen donor. The polymer type diphenyl ketone light initiator has phenoxyl or thiophenyl group resulting in relatively great red shift of ultraviolet absorption peak relatively to diphenyl ketone, and tertiary amine as hydrogen donor to omit introducing additional hydrogen donor for initiating polymerization. The present invention is superior to small molecular light initiator.
