摘要：
An ion exchange resin composition which comprises the reaction product of an epihalohydrin with a polyamine is alkylated. The polyamine has a molecular weight of from about 60 to about 298. This invention also encompasses a process for preparing the ion exchange resin composition which comprises reacting from about two-thirds of a stoichiometric amount of epihalohydrin to one and one-half times the stoichiometric amount of epihalohydrin with defined polyamines and thereafter reacting the resultant polymer with an alkylating agent to yield the final product.
