ABSTRACT:
Novel crosslinked ion exchange resins derived from dimethylaminoethyl methacrylate are disclosed together with their process of manufacture by suspension polymerization preferably utilizing a trialkylamine phase extender. Trialkylamines are found to be useful generally as phase extenders for the preparation of other polymeric materials by the known methods of suspension polymerization.
