| 摘 要： | 我们曾对丙烯酸丁酯(BA)与醋酸乙烯酯(VAc)一步法乳液共聚合机理进行过研究,并对其胶膜及胶乳性能进行了表征。结果表明一步法共聚乳胶粒具有类似于“核壳结构”的形态,其内核由BA含量高的共聚物组成,外壳基本是PVAc均聚物,对此用不同的方法进行了验证。在此基础上我们以VAc-BA进行了半连续法乳液共聚合,以与一步法相比较,从而探讨反应过程与胶粒结构及材料性能的关系。

| Abstract: | Copolymerization of vinyl acetate and butyl acrylate was carried out by using semi-continuous emulsion process. Monomer conversion, particle size, particle number of latexes and micromolecular structure and thermodynamical properties of the copolymers were measured and compared with corresponding copolymers prepared through batch process. Results show that homogeneous copolymers and latex particles could be obtained by semi-continuous process and the properties of copolymers are very significantly different from those of batch copolymers. |
