| Abstract: | The macromolecular titanate coupling agent (MTCA) was synthesized from tetraisopropyl titanate (TPT) , the copolymer methylmethacrylate-butylacrylate-acrylic acid and stearic acid (or diisooctyl phosphate). The results of DMA and DTAshowed that the thermal stability and Tg of the composite were improved because of adding MTCA to PVC/CaVO3 composite. The SEM micrographs also indicated that microshear and tensile properties occured on the fracture surface of the composite. All of these results demonstrated that MTCA was an effective coupling agent for PVC/CaCO3 composite. |
