| 摘要 |
The invention relates to modified comb copolymers comprising special stru ctural units, produced by reacting SMA resins and optionally special copolym ers having an AB block copolymer structure with a mixture consisting of at l east one polyalkylene oxide monoamine and at least one amino alcohol, a mixt ure of at least one polyalkylene oxide monoamine and at least one N,N-disubs tituted diamine or a mixture of at least one polyalkylene oxide monoamine, a t least one N,N-disubstituted diamine and at least one polymer selected from the group consisting of monohydroxy-terminated polyalkylene oxides, monohyd roxy-terminated polyesters and monohydroxy-terminated block copolymers consi sting of polyalkylene oxide blocks and polyester blocks. The invention also relates to the subsequent reaction of the monohydroxy-terminated side chains of said comb copolymers to form phosphoric acid esters and to the reaction of the N,N-disubstituted amino-terminated side chains of said copolymers to form quaternary ammonium salts. The invention further relates to the use of the copolymers as wetting agents or dispersants.
