| abstract |
The invention provides a method for producing a polymeric photoinitiator, of the general formula I: Polymer-[CR2-CHR-Spacer(PI) n ] m (I) wherein m is an integer from 1-5000; n is a real number above 0 and below 5; R is as defined herein, 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. |
