以丙烯酰胺、2-丙烯酰胺-2-甲基丙磺酸和甲基丙烯酰氧乙基三甲基氯化铵为共聚单体,引入各种功能性单体,以偶氮二异丁脒盐酸盐引发合成一种新型温控变黏酸稠化剂;研究了不同交联剂用量对温控变黏酸交联效果的影响,以及丙烯酰胺与2-丙烯酰胺-2-甲基丙磺酸重量比、甲基丙烯酰氧乙基三甲基氯化铵用量、丙烯腈用量对变黏酸温控变黏过程的影响,同时评价了温控变黏酸的交联与破胶降解能力。

Using acrylamide, 2-acrylamide-2-methylpropane sulfonic acid and dimethylaminoethyl methacrylate methyl chloride as the main comonomers, adding various functional monomers, a novel temperature-controlled variable viscosity acid viscosifier is synthesized with 2,2＇-azobis （ 2-methylpropionamide ） dihydroehloride as initiator. The effect of different crosslinker content on the cross-linking property of temperature-controlled variable viscosity acid is studied, and the effects of the quality ratio of acrylamide and 2-aerylamide-2-methylpropane sulfonic acid, the concentration of dimethylaminoethyl methacrylate methyl chloride and the content of acrylonitrile on the temperature-controlled viscosity change process for variable viscosity acid are investigated. Meanwhile, the abilities of cross-linking and degradation of temperature-controlled variable viscosity acid are evaluated.
