摘要：用细乳液聚合方法成功制备氢化松香甲基丙烯酸甲酯复合高分子乳液,考察聚合过程中氢化松香对单体转化率和聚合物粒子粒径的变化的影响,利用透射电子显微镜研究粒子的形态结构。结果表明聚合前后单体液滴的粒径和聚合物粒子的粒径基本保持不变;氢化松香的引入降低了聚甲基丙烯酸甲酯的分子量和玻璃化转变温度,加宽了分子量分布,其影响与理论预测的结果相一致。
Composite latex particles of hydro-rosin and poly （methyl methacrylate） PMMA were synthesized by miniemulsion polymerization. The influence of introduction of hydro-rosin on polymerization was studied by monitoring the evolution of monomer conversion and particle size. The particle morphology was characterized by transmission electron microscopy. The molecular weight, molecular weight distribution and the glass transition temperature of the resulted composite polymers were analyzed by gel permeation chromatography and differential scanning calorimetry. It was found that the diameter of the droplet and the polymer particles was almost the same before and after polymerization. The introduction of hydro-rosin reduced both the molecular weight and glass transition temperature of PMMA, which was highly accorded with the prediction from polymer theories.
