摘　　要：以过硫酸铵和亚硫酸氢钠为氧化还原引发剂,N,N-亚甲基双丙烯酰胺为交联剂,乙醇/去离子水为分散介质,聚乙烯吡咯烷酮(PVP)为分散剂,将丙烯酰胺和苯乙烯磺酸钠进行分散聚合制备了聚丙烯酰胺微球调剖剂,考察了乙醇/去离子水体积比、丙烯酰胺用量、引发剂用量、分散剂用量、交联剂用量、苯乙烯磺酸钠含量和反应温度对聚丙烯酰胺微球调剖剂的粒径和凝胶强度的影响。结果表明所合成的聚合物微球调剖剂粒径可调,平均粒径为1.0～8.5μm,具有较好的分散性和凝胶强度。FTIR谱图初步证实丙烯酰胺微球聚合物的结构。Polyacrylamide microsphere（PAM）, used as profile control agent, was prepared by dispersion copolymeri zation of acrylamide（AM）and sodium styrene sulfonate（SSS）, using ethanol/deionized water as dispersion medium, polyethylene pyrrole（PVP） as dispersant, N, N＇- methylenebisacrylamide（MBA） as crosslinker, ammonium persulfate and sodium bisulfite as redox initiators. Factors affecting particle size and gel strength of the microsphere, such as ethanol/deionized water volume ratio, AM amount, initiator amount, dispersant amount, crosslinking agent amount, SSS amount and reaction temperature were investigated. Results showed that the microsphere had adiustable particle size with average particle sizes of 1.0 - 8. 5μm, together with good dispersion and gel strength. FTIR spectrum indicated the structure of microsphere.
