Abstract

1421078 Photoinitiators ICI UNITED STATES Inc 18 Feb 1974 [16 March 1973] 7243/74 Heading C3P A photoinitiator for a mixture of polymerizable unsaturated polyester and a copolymerizable monomer has the general formula in which R 1 is H, Br or CH 3 , R 2 is H or Br provided at least one of R 1 and R 2 is Br and R 3 and R 4 are H or CH 3 ; an organic peroxide may also be added.
