The results show that the introducing of multivinyl monomer and CaCO3 can slow down polymerization rate to different extent.Using 1％～5％ trimethylolpropane trimetbacrylateor divinyl benzene,tight encapsulation of CaCO3 can be realized and beyond 94％PS cannot be extracted. The amount of crosslinker or emulsifier should be accommodated when the load amount of CaCO3 is increased.CaCO3 content in the product increases consequently with the increase of the loaded amount of CaCO3,which can be known from FT-IR and TGA.TEM observations reveal that when the load amount of CaCO3 is 14.8％,most CaCO3 particles are encapsulated and each latex particle contains one CaCO3 particle.Composite particles have well-defined core—shell structure and the thickness of polymer shells is around 10 nm.However,the thickness of polymer shell decreases and many free CaCO3 particles appear when the load amount of CaCO3 reaches 29.3％and 58.7％,respectively.

结果表明，多乙烯基单体以及碳酸钙的引入会使聚合反应速率有不同程度的降低；使用1%～5%的TMPTMA或DVB，可实现PS对碳酸钙颗粒的牢固包覆，不可抽提的PS达94%以上；当碳酸钙用量改变时，需要适当调整乳化剂和多乙烯基单体的用量；IR和TGA的结果表明，随着碳酸钙用量增加，产物中的碳酸钙含量也相应增加；TEM照片和计算结果显示，当碳酸钙用量为14.8%时，绝大部分碳酸钙颗粒被包覆，且基本上每个乳胶粒中包覆一个碳酸钙颗粒，复合粒子具有清晰的核壳结构，壳层厚度约为10 nm，而当碳酸钙用量增加到29.3%和58.7%时，壳层厚度减小，并且出现较多裸露的碳酸钙颗粒。

By measuring pressure induced by dynamiting which located various positions of the circular shell, the localizational effect of impact force on the circular shell is disclosed. Also, PVDF piezofilms are used to determine accurate time while projectile contacting target, accurate time while two interfaces of the target contacting at a initial distance of 5, and the contacting pressure between the two interfaces when the projectile is in 500m/s to lOOOm/s.
