摘要
将十六醇引入聚乙烯醇大分子中，合成了疏水缔合型增稠剂。流变性研究结果表明，改性的聚乙烯醇分子间存在相互缔合作用。５ ％ 改性聚乙烯醇溶液的粘度可达１６－０ Ｐａ·ｓ ，较未改性的聚乙烯醇增稠效果更好。
A hydrophobic associative thickener is synthesized by incorporating of a hexadecanol into the polyvinyl alcohol macromolecule It has shown, via rheology studies, that there exists associative actions among the modified polyvinyl alcohol molecules The viscosity of a 5% solution of the modified polyvinyl alcohol may be up to 16 0 Pa·s. Compared to the unmodified polyvinyl alcohol , it shows better thickening effect and salt resistance
