Abstract:
A process for preparing a polymer having quaternary ammonium groups which comprises polymerizing a vinyl monomer component (A) containing a vinyl monomer having a tertiary amino group of the formula (1): ##STR3## wherein X is --(CH.sub.2).sub.n -- in which n is an integer of 2 to 4, and R.sup.1 and R.sup.2 are independently an alkyl or hydroxyalkyl group having 1 to 9 carbon atoms, in a solvent (B) which dissolves said vinyl monomer component (A) but cannot dissolve a resulting polymer having quaternary ammonium groups and which is inert to the polymerization, while quaternizing said tertiary amino group (1) with a quaternizing agent (C).
