| 摘要 |
Polymeric products are prepared polymerizing in aqueous medium under addition polymerization conditions a dispersed phase of a polymerizable, ethylenically unsaturated monomer or mixture of polymerizable, ethylenically unsaturated monomers in the presence of a quaternary ammonium base group-containing polymer which is formed from reacting a polyepoxide with an unsaturated tertiary amine in the presence of a proton source. The polymeric products are useful in water-based coating compositions particularly for use in cationic electrodeposition.
