缔合型增稠剂的结构、性能及增稠机理研究进展

摘要

缔合型增稠剂是一种水溶性聚合物,在临界缔合浓度以上,形成以分子间缔合为主的超分子结构,增大了流体力学体积,因此具有较好的增稠性,是新一代的增稠剂.本文主要介绍了疏水缔合水溶性聚合物的结构及溶液性质,具体讨论了影响疏水缔合水溶性聚合物的增稠性能的多种因素,包括聚合物的结构和组成,分子量,离子基团,温度,剪切速率,表面活性剂.%The associative thickener is a water-soluble polymer,it's with good thickening because the associative thickener forms supramolecular structures based on the intermolecular association which increases the hydrody-namic volume when it 's above the critical aggregation concentration. This paper mainly introduces the structure and solution properties of hydrophobically associating water - soluble polymer,specifically discusses a variety of factors that affect the thickening properties of the polymer ,including the structure and composition of the polymer molecular weight,ionic groups,temperature,shear rate,the surface active agent.
