Results of studies of ..gamma..-induced grafting of p-styryl diphenyl phosphine (SOP) to polyvinylchloride (PVC), polypropylene and crosslinked polystyrene beads are described. SOP dissolved in dioxane-methanol radiation grafts readily to PVC at close rates up to 1.5 Mrad, and a Trommsdorff peak was observed at about 28% v/v monomer concentration under experimental conditions set forth here. SOP was found to be much more efficient in radiation grafting than vinyl phosphine. A photosensitized process using uv radiation was also investigated, and SOP was found to copolymerize easily to PVC and crosslinked polystyrene. The copolymerized SOP is useful for attachment of metal ions to yield catalysts suitable for hydrogenation reactions. Data for hydrogenation of cyclohexane using such catalysts showed as much as 30% conversion of the cyclohexane using chlorocarbonyltris(triphenylphosphine) iridium as catalyst. (BLM)
