ABSTRACT PREPARATION OF KETONE CONTAINING PHOTODEGRADABLE POLYMERS Process comprising pendant ketone functional moieties, are prepared by exposing a .beta.-substituted ketone compound corresponding to the formula: XCH2-CHR'-C(O)R wherein X is a suitable leaving group, R' is hydrogen or R; and R is alkyl or aryl of up to 12 carbons to vinyl ketone monomer formation conditions to prepare the corresponding vinyl ketone monomer and subsequently exposing a mixture thereof with an ethylenically unsaturated addition polymerizable monomer to addition polymerization conditions to prepare the resulting polymer. The vinyl ketone monomer can be formed in situ or in a preliminary step. 38,283-F
