摘要： Disclosed is a method for making polystyrene with M.sub.w between about 200 and about 50,000 and M.sub.w /M.sub.n ratio of less than about 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. For example, a polystyrene of about 13,000 M.sub.w and M.sub.w /M.sub.n of about 4.9 is prepared by contacting styrene monomer with BF.sub.3 in 4 stages between a temperature of about 60.degree. C and about 80.degree. C.
摘要翻译：公开了通过在基本等温条件下通过阳离子聚合苯乙烯单体制备聚苯乙烯，其Mw约为200至约50,000，Mw / Mn比小于约8的方法，其中苯乙烯单体的转化率在2个或更多个阶段通过接触进行与阳离子发生器。聚苯乙烯产品用作高分子量聚苯乙烯的增塑剂，作为各种涂料应用中的粘合剂树脂，以及作为其它官能化聚苯乙烯衍生物的前体。例如，通过在约60℃至约80℃的温度下使苯乙烯单体与BF 3在4个阶段接触来制备约13,000MW的Mw和Mw / Mn约为4.9的聚苯乙烯。
