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 hydrodynamic 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.
