Abstract
This article describes the copolymerization of styrene-butylmethacryla te (St-BMA) and the homopolymerization of styrene (St) in a counterrot ating twin screw extruder. The effect of prepolymerization on both the product properties and process was studied. It turned out that the pr ocess of reactive extrusion was strongly influenced by prepolymerizati on. Also, the product properties were altered by prepolymerization. Wh en the polymerization of St is compared with the copolymerization of S t-BMA, the process of St was more stable, although the polymerization rate was lower. (C) 1997 John Wiley & Sons, Inc.
