摘要
以丙烯酸钠(AANa)、乙酸乙烯酯(VAc)和甲基丙烯酸三氟乙酯(TFEMA)为单体进行无皂乳液聚合,合成了P(AANa-VAc-TFEMA)纳米含氟乳液,考察了反应温度、引发剂用量、单体配比对聚合的影响,并着重对聚合物乳液的粒径进行了研究。结果表明:该聚合单体的转化率可达到97.00%以上,聚合得到的无皂乳液稳定性好、粒径分布均匀。通过控制单体配比中AANa的含量及VAc与TFEMA的比例,可以得到纳米含氟乳液。
Copolymer of sodium acrylate（AANa）, vinyl acetate（VAc）and 2,2,2-trifluoroethyl methacylate（TFEMA）[P（AANa/VAc/TFEMA）] nano-sized fluorine-containing latex was produced by soap-free emulsion copolymerization of AANa, VAc and TFEMA. The effects of the reaction temperature, initiator dosage and monomer ratio on the polymerization was studied, with an emphasis on the latex particle size. The results indicate that the monomer conversion can reach above 97.00%, and the latex with good stability and uniform particle size distribution is obtained. In addition, nano-sized fluorine-containing latex can be produced by adjusting the content of AANa and the molar ratio of VAc to TFEMA in the feed.
