NEW STYRENE POLYMERS WITH KETO-ENOL SIDE- CHAINS .2. SYNTHESIS AND POLYMERIZATION OF BETA-BETA-TRIKETONE MONOMERS

New styrenic beta-beta-ketones: 1-(p-vinylphenyl) hexane-1,3,5-trione (1), 1-(p-vinylphenyl)-5-phenylpentane-1,3,5-trione (2) and 2-p-vinylb enzoylindane-1,3-dione (3) are described. Their ability to homopolymer ize and copolymerize with styrene has been tested; while homopolymers are insoluble resins of low interest for further photoreticulation, co polymers of 1 and 2 with styrene have been shown to be photoreticulabl e soluble products. Soluble (co)polymers of 3 have not been produced. Identifications of monomers and polymers (elemental analysis, IR, UV, H-1 NMR and C-13 NMR spectroscopies, steric exclusion chromatography) have made possible the evaluations of the Various ketoenols distributi ons in monomers and polymers and of the Alfrey Price parameters.
