摘　　要：以自制的带疏水链的聚氧乙烯醚甲基丙烯酸酯作为功能单体,采用半连续乳液聚合反应法,合成出一种无有机溶剂的疏水缔合型乳液聚合印花增稠剂,并对其结构和性能进行表征。结果表明,自制疏水缔合乳液聚合增稠剂的碱增稠能力和耐电解质性能优异。A hydrophobically associating emulsion polymerization thickening agent without organic sol⁃vent is synthesized by using a self-made hydrophobic polyoxyethylene ether methacrylate as a hydro⁃phobic functional monomer and semi continuous emulsion polymerization.The structure and properties of the thickening agent are characterized.The results show that the hydrophobically associating emul⁃sion polymerization thickener has excellent alkali thickening and electrolyte resistance.
