ABSTRACT:
Crosslinked basic polymers useful as weak base ion exchange resins are prepared by reaction, in the presence of an alkali, of a crosslinked aromatic polymer matrix which contains haloalkyl groups, with an oxy compound selected from: ##STR1## to provide a polymer predominating in repeating units of the formula: ##STR2## where R is the residue of said oxy compound, x, y and z are integers of from 1 to 3, R.sup.1, R.sup.3, and R.sup.4 independently are hydrogen or alkyl, and R.sup.2 and R.sup.5 are each alkylene.
