PRODUCTION OF POLYBUTADIENE RUBBER COMPOSITION

摘要

PURPOSE: A process for preparing the titled compound by continuously blowing oxygen or air during the reaction, coating stearic acid and producing zinc diacrylate or dimethacrylate is provided which reduces reaction time and produces polybutadiene rubber composition useful for the manufacture of a golf ball. CONSTITUTION: This process comprises the steps of pouring a mixture solution of acrylic acid and methylhydroquinone as a polymerization preventing agent into zinc oxide slurry under conditions of a reaction temperature of 60 to 120 deg.C and continuously blowing air or oxygen; preparing zinc diacrylate coated with stearic acid by adding stearic acid during ageing; and adding 10 to 50 parts by weight of the zinc diacrylate coated with stearic acid as a cocross-linking agent based on 100 parts by weight of the polybutadiene rubber composition and polymerizing.
