LAS与聚醚复合乳液体系中苯乙烯的聚合

Synthesis of polystyrene in mixture emulsion system of LAS and polyether

苯乙烯的初始浓度为36·33%时,在十二烷基苯磺酸钠(LAS)/聚醚复合乳液体系中制备了粒径在90·1nm、多分散系数在0·1的聚苯乙烯纳米微球。用红外光谱仪、透射电子显微镜、Zeta电位粒度仪对产物的化学结构,粒径大小、形貌,单分散性进行了表征。研究了体系中各组分质量浓度的改变对产物粒径及单分散性的影响。

With styrene＇s original concentration at 36. 33%, nanometer-sized particle with a diameter of 90nm was synthesized in mixture emulsion system of LAS and Polyether. The chemical composite was identified by IR and the particle size and monodispersity was measured by Zetaplus and TEM. The influence of concentration of constitutes in system was also studied.
