Abstract

The authors prepared the resin of vinyl chloride grafted by acrylate copolymer (ACR-g-YC) via in-situ suspension polymerization and the composites consisting of ACR-g-VC and nano-hydrotalcite. Morphology, processability, mechanical properties and thermal properties of the resultant composites were studied. Nano-hydrotalcite existed mainly in the primary particle form in poly (vinyl chloride) (PVC) matrix of the ACR-g-VC/nano-hydrotalcite composites prepared via in-situ polymerization/melt processing, and their dispersivity was obviously superior to that of the nano-particles in the composite prepared by direct melt blending of ACR-g-VC with the nano-hydrotalcite. The content of nano-hydrotalcite had slight influence on the impact strength and the storage modulus of the composites prepared via in-situ polymerization/melt processing, while the plastic processability and thermal stability of ACR-g-VC improved with amount of the nano-hydrotalcite incorporated in the polymerization. The temperature of 10% loss in mass of the composite containing 2% of nano-hydrotalcite in mass increased nearly by 20°C in comparison with that of PVC, and the plasticization time of the composite was shortened to 22 seconds.
