【摘要】 以纳米 Si O2 为核 ,以 MMA为壳层单体 ,进行了无皂乳液聚合。研究了单体加入方式、引发剂用量、聚合反应温度等对无皂乳液聚合的影响。核壳产物对 PVC材料的力学性能有明显的提高。更多还原

【Abstract】 Studied the emulsifier-free emulsion polymerization in which consisted of nano-SiO 2 particles as core and MMA as shell,the effect of the quantity of MMA and polymerization’s temperature on emulsifier-free emulsion polymerization and the mechanical properties of PVC filled with nano-SiO 2/MMA particles. The results showed that nano- SiO 2/MMA in PVC improved the mechanical properties of the composites greatly.更多还原
