A thermoreversible thickener comprising a watersoluble copolymer containing as the constituent unit at least 50 wt.% of a vinylcarboxylic ester of an alkylene oxide adduct of a cyclic amine or a C₅ or higher acyclic amine. It has a thickening initiating temperature that can readily be adjusted according to the object of its use and also has a thickening effect which rises steeply as the temperature rises above the transition temperature. A composition comprising 0.01-30 wt.% of this thickener and 70-99.99 wt.% of an aqueous solution, emulsion or dispersion containing an organic or inorganic substance is utilizable for producing a coating composition, rolling oil composition, (pressure-sensitive) adhesive, printing ink, paper coating material, carpet backing adhesive, and so on.
一种热可逆增稠剂,由一种水溶性共聚物组成,该共聚物的组成单元中至少含有 50 wt.%的环胺或 C₅或更高无环胺的环氧化亚烷基加合物的乙烯基羧酸酯。它的增稠起始温度可根据使用目的进行调节,而且随着温度升至过渡温度以上,增稠效果会急剧上升。由 0.01-30 重量百分比的该增稠剂和 70-99.99 重量百分比的含有机或无机物质的水溶液、乳液或分散液组成的组合物可用于生产涂料组合物、轧制油组合物、(压敏)粘合剂、印刷油墨、纸张涂层材料、地毯背衬粘合剂等。
