    • Water-soluble, biologically degradable copolymers based on polyamide are described which contain at least one grafted side chain composed of aldehydes and sulfur-containing acids and salts thereof and optionally at least one compound from the series ketones, aromatic alcohols, urea (derivatives) and amino-s-triazines. Natural polyamides such as caseins, gelatins, collagens, bone glues, blood albumins and soya proteins as well as degradation products thereof and synthetic polyamides such as polyaspartic acids and copolymers of aspartic and glutamic acid are used as preferred polyamide components. These copolymers are obtained primarily by graft polymerization at temperatures between −10 and 250° C., preferably in the presence of a solvent such as water or by thermal drying and they are used in particular as flow agents or water retention agents for inorganic binders and pigments especially in combination with hydraulic binders they only have a very slight setting-retardant effect.
    • 描述了基于聚酰胺的水溶性生物可降解共聚物,其含有至少一个由醛和含硫酸及其盐组成的接枝侧链,以及任选的至少一种来自串联酮,芳族醇,脲(衍生物)和 氨基-s-三嗪。 天然聚酰胺如酪蛋白,明胶,胶原,骨胶,血液白蛋白和大豆蛋白以及其降解产物和合成聚酰胺如聚天冬氨酸和天冬氨酸和谷氨酸的共聚物被用作优选的聚酰胺组分。 这些共聚物主要通过在-10至250℃的温度下接枝聚合,优选在溶剂如水或通过热干燥的存在下获得,并且它们特别用作无机粘合剂的流动剂或保水剂, 颜料特别是与水性粘合剂组合,它们只具有非常轻微的阻燃效果。
