| Abstract: | The surface properties of nano CaCO 3 which was modified by a serious of surfactants have been investigated. The modified CaCO 3's surface polarity was changed from hydrophilicity to lipophilicity. The viscosity of modified CaCO 3/DOP and the oil absorption rate of modified CaCO 3 decreased remarkably. The modified nano CaCO 3 had been used in soft PVC. The mechanical properties and processabilities of the PVC have been tested. |
