Procedure

50 parts by weight of xylene is placed in a three-necked plask, and 75 parts by weight styrene, 20 parts by weight butyl acrylate, 5 parts by weight butyl maleate, 0.6 parts by weight divinylbenzene and 0.3 parts by weight benzoyl peroxide are added through a dropping funnel under reflux over 3 hours. Then a solution of 0.3 parts by weight benzoyl peroxide in xylene is dropwise added and refluxing is continued for 3 hours followed by cooling and removing the xylene to give a styrene-butyl acrylate-butyl maleate-divinylbenzene copolymer. Gel content of the resulting polymer is 0%.
