摘 要: 将甲基丙烯酸甲酯(MMA)与丙烯酸(AA)按不同比例混合,接枝到聚丙烯酸丁酯橡胶粒子上制备核壳乳液,用浊度法通过测量各乳液的临界聚沉浓度(CCC)值来考察AA的含量对乳液的稳定性影响。结果表明AA占总反应物的0%~3%时,随AA含量的增加,CCC值增大,乳液的稳定性也增大。 The stability of core-shell particles with butyl acrylate (BA) as the core and methyl methacrylate (MMA)/acrylic acid(AA) mixture in various compositions as the shell was investigated by critical coagulation concentration (CCC) values which were got through turbidity measurement. The experiments demonstrate that the latexes stability was improved by the addition of AA from 0 to 3%, and the CCC values increase.
