Abstract
Compounds represented by the formula: ##STR1## wherein R.sup.1 is alkyl, aralkyl, alkoxyalkyl, alkenyl, alkynyl, carboxyalkyl or carboxyaryl; PA1 R.sup.2 is any group which does not cause spontaneous decomposition of the peroxy group; and PA1 x and y are integers between 0 and 4 with x+y great than or equal to 1, are disclosed. The inventive compounds are useful as visible and UV photoinitiators and as thermal or chemical initiators for curing compositions of ethylenically unsaturated monomers and prepolymers.
