Procedure

Pure water and polyvinyl alcohol as a suspending agent were charged in amounts of 35 kg and 320 g into an autoclave having a volume of 50 l to prepare an aqueous medium. After dissolving 180 g of benzoyl peroxide in 10.8 kg of styrene (SM) and 7.2 kg of isononyl acrylate (INA), the obtained mixture was added to the medium and the mixture was stirred to prepare a suspension. After nitrogen was introduced into the autoclave in order to substitute its interior with nitrogen, the autoclave was heated to 60° C. The suspension was stirred at this temperature for 5 hours to perform prepolymerization. The autoclave was heated to 90° C. while increasing the stirring speed. The suspension was then stirred at this temperature for 3 more hours to complete polymerization. After cooling, the solid content of the autoclave was removed therefrom and washed with water to provide 17.5 kg of a styrene-isononyl acrylate copolymer (SAE). The obtained SAE had a styrene content of 60% by weight, and an isononyl acrylate content of 40% by weight.
