Abstract

Polymerization conditions in the Pickering emulsion of colloidal silica-stabilized polystyrene latex were optimized. The influence of process conditions on various parameters, including particle size and distribution was investigated. Monomodal particles distribution was obtained by conducting the process at a temperature of 80°C in a slightly acidic environment (pH = 5), while maintaining fast monomer conversion. It has been shown that the amount of stabilizer used in the polymerization process affects the rate of polymerization, therefore the temperature of the process should be adjusted to the amount of colloidal silica used in the process.

苯乙烯酸洗乳液聚合制备α功能化聚苯乙烯乳液:参数和工艺条件

对胶体硅稳定聚苯乙烯乳胶皮克林乳液的聚合条件进行了优化。考察了工艺条件对颗粒粒度和分布等参数的影响。在微酸性环境(pH = 5)下，在温度为80℃的条件下进行该工艺，在保持单体快速转化的情况下，获得了单模态的颗粒分布。研究表明，在聚合过程中稳定剂的用量会影响聚合的速度，因此应将工艺温度调整到与工艺中胶体二氧化硅用量相适应。
