実験手順
A liquid mixture consisting of 4.7 parts by weight of acrylonitrile, 73.3 parts by weight of styrene, 22 parts by weight of ethylbenzene and 0.02 parts by weight of t-butylperoxy-isopropyl carbonate employed as a polymerization initiator was supplied continuously into a complete mixing-type reactor (capacity: 5 liter) at a flow rate of 2.5 liter/hr and polymerization was performed at 142° C. until the degree of polymerization reached 60%. Then the polymer solution was fed continuously into a vent-type extruder where the unreacted monomers and the solvent were removed therefrom at 260° C. and 40 Torr. Next, the polymer was continuously solidified by cooling and cut into pieces to give a particulate styrene/acrylonitrile copolymer (referred to as AS-1). When analyzed by IR absorption spectrometry, this copolymer was composed of 9% by weight of the acrylonitrile unit and 91% by weight of the styrene unit and had a melt flow rate of 90 g/10 min (measured at 220° C. with a load of 10 kg in accordance with ASTM D-1238). This copolymer is referred to as AS-1 hereinafter.
