| 摘要 |
<p>The invention relates to a method of making waterborne multifunctional materials, especially waterborne multifunctional materials comprising at least one primary carbamate group and a grafting moiety (cii). The method of the invention requires the successive or simultaneous reactions of a material P with a grafting material (c) and ammonia. Material P comprises two or more cyclic carbonate groups (bi). Grafting material (c) comprises at least one amine group (ci) and a grafting moiety (cii). The amine group (ci) is selected from primary amines, secondary amines, and mixtures thereof. The resulting waterborne multifunctional materials may be water dispersible, water soluble and/or useful in electrodeposition coatings.</p> |
