Procedure

In 100 g of water placed in a 200 ml-volume flask were dissolved 0.1 g of polyvinyl alcohol (degree of polymerization of 1700 and degree of saponification of 88%) and then 4 g of sodium chloride. Into the solution were added 19.8 g of 2-ethylhexyl acrylate, 0.5 g of methacrylic acid, 1.25 g of methyl methacrylate, 0.005 g of dodecyl mercaptan, and 0.1 g of lauroyl peroxide. The mixture was allowed to polymerize at temperature of 60° C. for 6 hours. The resulting suspension particles were separated by filtration, washed with water and dried, to give 2-ethylhexyl acrylate/methacrylic acid/methyl methacrylate copolymer.
