研究了引发剂浓度、聚合介质离子强度、聚合温度和单体/水比对苯乙烯、甲基丙烯酸甲酯和甲基丙烯酸缩水甘油酯无皂乳液聚合产物粒径、粒径分布和分子量的影响。通过研究发现了制备粒径大于1 μm的均匀聚苯乙烯粒子的最佳条件，但由甲基丙烯酸酯单体和交联粒子合成粒径相近的单分散粒子的尝试失败了。结果表明，“非活化”胶乳颗粒的溶胀能力不超过70倍的体积增加，并强烈依赖于原始颗粒的大小。
The effects of initiator concentration, ionic strength of polymerization medium, polymerization temperature, and monomer/water phase ratio on particle size, particle size distribution and molecular weight of the resulting polymers prepared by an emulsifier-free emulsion polymerization of styrene, methyl methacrylate and glycidyl methacrylate have been studied. Optimal conditions for preparation of uniformly sized polystyrene particles larger than 1 μm have been found. An attempt to synthesize monodisperse particles of similar size from methacrylate monomers and crosslinked particles has failed. It is shown that the swelling ability of “non-activated” latex particles does not exceed 70 fold increase in the volume and strongly depends on the size of the original particles.
