摘要
利用超声波分散、乳化、引发、还原等作用,及单体2-丙烯酰胺基-2-甲基丙磺酸(AMPS)的特有结构,实现了超声引发AMPS、甲基丙烯酸甲酯(MMA)和氯化钯(PdC l2)的两相同步原位无皂乳液聚合,制备了纳米P(AMPS-MMA)/Pd复合粒子,考察了反应过程中pH、超声时间、超声功率对单体转化率的影响规律,并借助于FT-IR、TEM、XRD等相关分析方法对产物进行了表征.
Utilization the particular actions of ultrasonic wave, including dispersion, emulsification, initiation, and the special structure of 2-acrylamido-2-methylpropanesulfonic acid (AMPS) molecular chain, poly (AMPS) -co- ( metheyl methacrylate)(MMA) composite nanoparticles are synthesized by two phase synchronous situ emulsion- free polymerization without initiator, reduetant and emulsifier. The effect of pH value,output power of the ultrasonic and ultrasonic time on conversion rate of monomer is studied respectively. The mierostructure of composite particles is characterized by TEM, FT-IR, and XRD.
