Abstract

The polymerization of styrene in the presence of an organosilicon comb-shaped surfactant, α,ω‑bis(trimethylsiloxy)-oligodimethylmethyl-(10-carboxydecyl)siloxane, is studied. The reaction yields aggregatively stable polystyrene suspensions with a polymer content of up to 50%, a high surface concentration of carboxyl groups, and a particle diameter of up to 2.2 μm. A comparative analysis of the kinetic regularities of polymerization and the properties of polymer suspensions in the presence of the comblike, dimeric, and linear surfactants is carried out.

摘要

研究了在有机硅梳状表面活性剂 α,ω-双(三甲基甲硅烷氧基)-低聚二甲基甲基-(10-羧基癸基)硅氧烷存在下苯乙烯的聚合反应。该反应产生聚合稳定的聚苯乙烯悬浮液，聚合物含量高达 50%，羧基的表面浓度高，粒径高达 2.2 μm。在梳状、二聚和线性表面活性剂存在下，对聚合的动力学规律和聚合物悬浮液的性质进行了比较分析。
