| 摘 要： | 采用自制的属于Gemini型的特殊乳化剂KD-1用于苯乙烯丙烯酸酯微乳液的聚合。研究了反应温度、乳化剂用量和单体含量对微乳液聚合的影响。结果表明,只使用质量分数为0 95%～1 60%的单一阴离子型乳化剂KD-1就可得到较高固含量(质量分数为30%～50%)的透明纳米级苯乙烯丙烯酸酯微乳液,并保持微胶乳平均粒径为40～60nm。与常规苯乙烯丙烯酸酯乳液相比,其粒径小,最低成膜温度有所降低,而玻璃化转变温度有所提高。

| Abstract: | Preparation of styrene-acrylic microemulsion was studied by using self-prepared surfactant KD-1,which was one of the special Gemini anionic surfactants.Effects of reaction temperature,surfactant concentration and monomer concentration on polymerization were studied.By using low concentration single surfactant,w=0.95%—1.60% only,a transparent copolymer latex with high solids-content (w=30%—50%) and small particle diameter (40—60 nm) could be obtained.In comparison with conventional emulsion polymerization product,the prepared microemulsion latex was much smaller in particle diameter,with lower film forming temperature and higher glass transition temperature. |
