Procedure

A monomer mixture comprising 600 g of styrene (hereinafter referred to as "St") and 70 g of glycidyl methacrylate (hereinafter referred to as "GMA") was dissolved in 1000 g of methyl ethyl ketone (hereinafter referred to as "MEK") in a four -necked flask fitted with a dropping funnel, a nitrogen inlet tube, a thermometer, a condenser and a stirrer and the solution was heated to 70° C. Another monomer mixture comprising 15 g of azobisisobutyronitrile (hereinafter referred to as "AIBN") as the polymerization initiator, 260 g of St, 70 g of maleic anhydride (hereinafter referred to as "MAH") and 280 g of MEK was stepwise dropped thereinto to initiate polymerization. After 10 h, the flask was cooled to room temperature arid the reaction mixture was immediately poured into a large quantity of methanol. The polymer thus precipitated was recovered by decantation, dried under reduced pressure in a vacuum drier axed Finely pulverized to give 870 g of styrene-maleic anhydride glycidyl methacrylate copolymer (3). According to GPC, the copolymer (3) had a number-average molecular weight (in terms of polystyrene ) of 15,000. The infrared absorption spectrum of the copolymer (3) is given in FIG. 1.
