The present invention relates to pulverulent and film-forming compositions that comprise at least one film-forming polymer prepared from at least one amide of an ethylenically unsaturated acid and at least one further ethylenically unsaturated monomer, wherein at least a portion of the at least one amide of an ethylenically unsaturated acid is homopolymerized in the absence of the at least one further ethylenically unsaturated monomer. The compositions further comprise at least one aromatic acid according to Formula (I)
wherein:
A comprises a carboxylic acid group or a sulfonic acid group, and
X1 to X5 are each independently selected from hydrogen, group A as defined above, group B comprising a hydroxyl or amino group, linear or branched C1-C10 alkyl, which may optionally be substituted with one or more heteroatom-containing functional groups but being different from groups A or B, and C1-C10 alkoxy, under the proviso that at least one of X1 to X5 is group B,
or a salt of the aromatic acid of Formula (I).
The preparation and uses of such compositions e.g. in the production of construction materials are also disclosed.
本发明涉及包含由至少一种乙烯基不饱和酸酰胺和至少一种乙烯基不饱和单体制备的至少一种成膜聚合物的粉碎和成膜组合物,其中至少一部分乙烯基不饱和酸酰胺在没有至少一种乙烯基不饱和单体的情况下均聚。组合物还包括至少一种符合式(I)的芳香族酸
其中
A 包括一个羧酸基团或一个磺酸基团,以及
X1 至 X5 各自独立地选自氢、如上定义的基团 A、包含羟基或氨基的基团 B、直链或支链 C1-C10 烷基(可任选被一个或多个含杂原子的官能团取代,但不同于基团 A 或 B)以及 C1-C10 烷氧基,但条件是 X1 至 X5 中至少有一个是基团 B、
或式(I)芳香酸的盐。
此外,还公开了此类组合物的制备方法和用途,例如在建筑材料生产中的应用。
