| 摘要 |
<p>The present invention provides a co-polymer that is capable of forming sterically stabilised dispersions in aqueous media, comprising steric stabilising units having water soluble poly(oxyalkylene) chains, structural units and amine group containing units, the amine group containing units comprising tertiary amine groups or an acid salt thereof or quaternary ammonium salt groups; the amount of amine group-containing units being such that the co-polymer contains from 0.025 to 0.5 milli-equivalents of amine per gram of co-polymer. The co-polymers are useful as film-formers in their own right and also as steric stabilisers for other film-forming polymers in non-ionic electrodepositable coatings.</p> |
