摘要： An environmentally friendly stable aqueous optionally structured water-resistant architectural coating composition (especially a paint) containing a film-forming binder polymer composed of a starch modified by the presence of carboxylic acid or inorganic carboxylate groups and bonded (probably grafted) to chains of copolymerized mono-ethylenically unsaturated monomers (e.g. “acrylic”, “vinyl” or “styrenic” copolymers) permitting a stable aqueous dispersion of the binder polymer to be made which retains good water-resistance in the dried paint. The modified starch allows paints to be made with less dependence on materials obtained from non-renewable resources while retaining a low water-sensitivity.
摘要翻译：一种环境友好的稳定的含水任选结构的防水建筑涂料组合物（特别是涂料），其含有由羧酸或无机羧酸盐基团的存在改性的淀粉组成的成膜粘合剂聚合物，并将（可能接枝的）连接到共聚合链单烯属不饱和单体（例如“丙烯酸”，“乙烯基”或“苯乙烯”共聚物）），其允许制备粘合剂聚合物的稳定的水分散体，其在干燥的涂料中保持良好的耐水性。改性淀粉允许在对不可再生资源获得的材料的依赖性较小，同时保持低水敏感性的情况下进行涂料。
