【摘要】 聚丙烯酰胺（ＰＡＡＭ）及其衍生物是水溶性聚合物中较重要的物质，由于其独特的物理化学性能，可作为油田化学助剂、絮凝剂、增稠剂、助滤剂、表面活性剂、土壤改良剂、纸质增强剂等，得到广泛应用［１，２］。为了保持高增粘性能的基础上，克服丙烯酰胺在三次采油中耐盐...更多还原

【Abstract】 Polymerization of acrylamide(AAm) initiated by the combination of N,N dimethyldiacrolamine chloride(DMDAAC) with ammonium persulfate was studied.The super high molecular weight,2.0×10 7 of PAAm was obtained by using above initiation system at 30℃,the AAm concentration being 20%.The reservation ratio of viscosity for PAAm was 24.4% in the saline solution of 0.1mol/L.The PAAm initiated by this initiation system showed better viscous and salt resistant properties.更多还原
