| Abstract: | Several new polymeric antioxidants have been synthesized based on 2,6-di-t-butyl-4-vinyl (or isopropenyl) phenol. They were prepared by emulsion copolymerization with 1,3-butadiene or isoprene and had about 6 to 10 mol% of the polymerizable hindered vinyl (or isopropenyl) phenol in the copolymers. The copolymers were catalytically hydrogenated in the presence of soluble cobalt catalysts to saturated copolymers of ethylene or ethylene/propylene structure. The polymers are apparently not branched and had molecular weights up to 50 000. |
