水溶性单体类型对BA-MMA-St微皂乳液性能的影响

Effect of Water-soluble Monomers on Properties of BA-MMA-St Emulsifier-minor Emulsion

用甲基丙烯酸(MAA)或丙烯酸(AA)和N-羟甲基丙烯酰胺(N-MA)或丙烯酰胺(AM)共聚,实现了BA-MMA-St的微皂乳液聚合。考察了水溶性单体(羧酸类单体、非离子水溶性单体)对微皂乳液聚合性能的影响。实验结果表明,采用微皂乳液聚合明显地改善了涂膜的耐水性和附着力。

The emulsifier-minor emulsion of BA-MMA-St was obtained by copolymerization of BA, MMA and St with methaerylie aeid（MAA） or acrylic acid（AA） and Nhydroxymethyl acrylamide （N-MA） or aerylamide （AM）. The effects of water-soluble monomers （carboxylic monomers and nonionic monomers） on the properties of emulsifi- er-minor emulsion were investigated. The results indicated that the water resistance and the adhesion power of the film were improved obviously by the polymerization of emulsifier-minor emulsinn
