摘要:

以丙烯酰胺(AM)为主单体,2-丙烯酰胺-2-甲基丙磺酸(AMPS)为功能单体,N,N'-亚甲基双丙烯酰胺(MBA)为交联剂,通过反相乳液聚合法制备了聚丙烯酰胺微球。优化反应较佳合成条件为:油水质量比13∶7,m(AM)∶m(AMPS)=7∶1,交联剂用量2.9%,引发剂用量0.06%,此时乳液平均粒径为278 nm,黏度最小。采用FT-IR、SEM、TG及RS6000流变仪对产物的结构、形貌和性能进行了分析。结果表明,成功合成了目标产物,乳液呈现高分散度的光滑微球,具有较好的黏弹性及耐温耐盐性能。

Abstract:

Polyacrylamide microspheres were prepared by inverse emulsion polymerization with acrylamide (AM) as the main monomer, 2-acrylamide-2-methylpropanesulfonic acid (AMPS) as the functional monomer, and N, N'-methylenebisacrylamide (MBA) as the crosslinking agent. The optimal conditions of synthesis were oil-water mass ratio of 13∶7, m(AM)∶m(AMPS)=7∶1, the amount of crosslinking agent of 2.9%, and the amount of initiator of 0.06%. The average particle size of the emulsion thus obtained was 278 nm with a minimum viscosity. FT-IR, SEM, TG and RS6000 rheometers were used to analyze the structure, morphology and properties of the products. The results showed that the target product was successfully synthesized. The emulsion exhibited smooth microspheres with high dispersity, and had good viscoelasticity and temperature and salt resistance.

Key words: inverse emulsion polymerization, polyacrylamide microsphere, blocking agent, viscoelasticity
