Polymeric quaternary ammonium salts containing specific cationic recurring units

摘要

Disclosed are novel polymeric quaternary ammonium salts containing specific di-tertiary amino substituted cationic recurring units. Said salts are useful as dyeing and finishing agents, especially for dyeing textile materials, such as polyacrylonitrile fiber materials, as dispersing agents and emulsifiers, as antistatic, antimicrobial and flocculating agents and as precipitants.
