Abstract

In concentrated polymer latex systems where strong repulsive forces, either electrostatic or steric, exist between the particles ordering of the particles occurs. The structure formed can be examined by small angle neutron scattering and experiments indicate that the arrangement of the particles is liquid-like. Results are reported for a poly(-styrene) latex in an aqueous electrolyte solution and for a poly(-deuteromethyl methacrylate) latex, with the particles stabilised by poly-12-hydroxy stearic acid in dodecane.

聚合物颗粒分散体的结构
在浓聚乳胶体系中,粒子之间存在强斥力,不论是静电斥力还是空间斥力,粒子的有序性就会发生。形成的结构可以用小角中子散射来检测,实验表明颗粒的排列呈液体状。本文报道了在电解质水溶液中的聚(-苯乙烯)乳胶和在十二烷中用聚12-羟基硬脂酸稳定颗粒的聚(-甲基丙烯酸二甲基)乳胶的实验结果。
