PROCESS FOR MAKING POLYSTYRENE

摘要

A method for making polystyrene with ?w between 200 and 50,000 and ?w/?n ratio of less than 8 by cationically polymerizing styrene monomer under substantially isothermal conditions where the conversion of styrene monomer is carried out in 2 or more stages by contacting with a cation generator. The polystyrene product finds utility as plasticizer for high molecular weight polystyrenes, as a binder resin in various coating applications, and as a precursor for further functionalized polystyrene derivatives. 18,105-F
