Abstract
The invention provides a method for producing a polymeric photoinitiator of the general formula I: Polymer-[CR2-CHR-Spacer (PI)], (I) wherein m is an integer from 1-5000; n is a real number above 0 and below 5; each R group, independently, is a substituent independently selected from hydrogen, C1-C25 linear alkyl, C3-C25 branched alkyl, C3-C25 cycloalkyl, aryl, heteroaryl, —OH, —CN, halogens and amines and PI is a photoinitiator moiety. The method comprises grafting one or more photoinitiator moieties (PI), each of which comprises at least one activated alkene functional group, onto the polymer. Polymeric photoinitiators are also provided.
