ABSTRACT:
An aminoalkoxystyrene represented by the formula (1)wherein R1and R2are C1-4alkyl and n is 3-6. The aminoalkoxystyrene is prepared by reacting an aminoalkoxyphenylmagnesium halide with vinyl halide in the presence of a catalyst. A quaternized amino group-containing polymer made by quaternizing the amino groups of a polymer prepared from the aminoalkoxystyrene is useful as an anion exchanger.
