【摘要】 采用溶剂热法 ,以AIBA为引发剂引发苯乙烯均聚 ,制得了小粒径的无皂阳离子乳胶纳米粒子。讨论了温度对乳胶粒径、反应时间对转化率的影响以及乳液的抗电解质稳定性 ,结果表明 :采用溶剂热法制得的无皂阳离子聚苯乙烯乳胶粒子粒径约为 2 5nm ,分散均匀 ;随着温度的升高粒径先减小后增大 ;乳液的稳定性好更多还原

【Abstract】 Emulsifier-free cationic polystyrene nanoparticles with the diameter about 25nm were prepared using 2,2′-aobis(2-ethylpropionamidine)dihydrochloride as initiator with solvothermal method in acetone-water medium. The results reveal that the particle diameter decreases and then increases, with increasing reaction temperature. The stability of microsphere is good.更多还原
