A high activity especially in the presence of TIBA was observed. The morphology was investigated by using raster electron microscopy （REM） showing that the CaCO3-nanoparticles are uniformly distributed. The melting temperatures and the crystallization temperatures are not much influenced by increasing filler content.展开更多
