ABSTRACT:
A process for preparing polymers having quaternary ammonium groups comprising polymerizing a vinyl monomer component containing a vinyl monomer having a tertiary amino group in the presence of a specific solvent, while quaternizing the tertiary amino group with a quaternizing agent, to produce the vinyl polymers having quaternary ammonium groups in the form of particles dispersed in the solvent, which is possible to easily separate the produced polymers having quaternary ammonium groups from the solvent without requiring a heating step for removing the solvent, and which can produce quaternary ammonium group-containing copolymers having a high content of a hydrophobic vinyl monomer. The quaternary ammonium group-containing copolymers obtained by this process are useful as modifier for plastics, permanent antistatic agent, bactericide or fungicide, chemicals for paper making and water treating agent.
