含氟丙烯酸酯共聚乳液的制备及表征

Preparation and Characterization of Fluorine-Containing Copolymer Emulsion

摘要: 采用十二烷基硫酸钠和壬基酚聚氧乙烯醚(OP-10)混合乳化剂，制备了粒径为40-50nm的甲基丙烯酸全氟辛基乙酯(FMA8)-甲基丙烯酸丁酯(BMA)-甲基丙烯酸(MA)共聚物乳液。通过DSC、、FTIR、^1H-NMR等手段对共聚物进行了表征。考察了乳液的稳定性、乳胶膜的吸水性和耐溶剂性以及全氟单体的含量对聚合反应的影响。

Abstract: Stable copolymer latex with range of 40-50 nm were prepared by emulsion polymerization of fluorinated monomer FMA8 with BMA and MAA using SDS and OP-10 as emulsifier. Hie copolymer was characterized by DSC.FT-IR and 'H-NMR. The water absorption ability of
