摘要/Abstract

摘要： 以醋酸乙烯酯(VAc)、甲基丙烯酸（MAA），丙烯酸丁酯（BA）为单体，使用半连续乳液聚合法，合成了适用于醋酯长丝上浆的浆料，测试合成浆料的含固率、浆液粘度、单体转化率以及浆膜的耐水性能，然后采用单因素分析法研究了影响聚合的几个因素，得出了合理的合成工艺，并用红外光谱仪对共聚物的结构和性能进行了表征。结果表明，当引发剂(APS）相对于单体为0.75%，复合乳化剂（OP-10:SDS为3:1）相对于单体为3%，半连续滴加时间为4h时，聚合乳液的性能最好。

Abstract: The sizing agent for acetate filament was synthesized by using vinyl acetate, methacrylic acid and butyl acrylate as monomers and adopting semi-continuous emulsion polymerization method. Solid content of the polymer, viscosity of size pastes conversion rate of monomers and water resistance of sizing film were tested. Then using single factor analysis to optimize these influencing factors, the best synthesizing process was established. Besides, the structure and properties of the polymer were analyzed by FTIR. Experimental results indicate that the property of copolymer emulsion is excellent with 0.75% initiator (APS, based on the total monomer), 3% complex emulsifier (OP-10:SDS is 3:1) and 4 hours of dropwisetime.
