摘要：采用反相乳液聚合法,以液体石蜡为连续相、丙烯酰胺水溶液为分散相、N,N′-亚甲基双丙烯酰胺为交联剂、过硫酸铵为引发剂、Span-80和OP-10为复合乳化剂,制备了丙烯酰胺均聚物(PAM);考察了溶剂、交联剂及其用量、氮气、单体浓度、乳化剂种类、油水比、引发剂用量对PAM均聚物性能的影响.较佳的聚合条件为:交联剂的用量为单体质量的2.5%,单体AM的含量为40%,油/水质量比接近1.0,引发剂过硫酸铵为单体含量的0.9%,使用复合乳化剂Span-80/OP-10,HLB=5.35.在此聚合条件下,制得的PAM均聚物的粘度较大,稳定性较好.
By reverse phase emulsion polymerization,in liquid paraffin wax for continuous phase and acrylamide solution for the dispersed phase,N,N ＇and methyl double acrylamide as crosslinking agent,ammonium persulfate as the initiator,Span 80 and OP-10 as compound emulsifier,preparation for the acrylamide（PAM） are homopolymers;Examine the solvent,crosslinking agent and dosage,nitrogen,monomer concentration,emulsifier types,oil and water ratio,the initiator of PAM dosage influence on the performance of the thing all together.Better polymerization conditions for： the amount of crosslinking agent for 2.5% of the mass of monomer,monomer AM content is 40%,oil/water weight than close to 1.0,the initiator ammonium persulfate as monomer content of 0.9%,use compound emulsifier Span 80/OP-10,HLB = 5.35.On the polymerization conditions,the system of the viscosity of the homopolymers PAM are larger,stability is good.
