摘　　要：首先优化了丙烯酰胺(AM)和二甲基二烯丙基氯化铵(DMDAAC)共聚物的合成条件.在此基础上,研究了加入少量扩链剂组分后新型酸液稠化剂的制备.实验主要探讨了扩链剂的浓度和加入时机对稠化剂性能的影响.通过红外光谱、差热分析表征了合成共聚物的分子结构,并对其稠化性能进行了评价.结果表明:通过扩链剂的加入,使合成聚合物的稠化性能大大提高,且在酸化过程中对酸液具有"适时"稠化能力.The synthesis conditions of acrylamide(AM) and dimethyl diallyl ammonium chloride(DMDAAC) copolymer are optimized.Based on this,a new thickeneer is prepared by adding a chain extender to the copolymer.The effects of the concentration and adding time of the chain extender on its thickening performance are studied.The molecular structure of the copolymer is characterized by infrared spectrum and differential thermal analysis,and the thickening performance of it is also evaluated.It is shown that the thickening performance of the new thickener is greatly improved by adding the chain extender and it can timely thicken acid liquid during acidification.
