Abstract: DSC, TGA and TMA techniques are used for systematical study of glass transition, thermal degradation, thermal oxygen degradation, HCl removal process and deformation characteristics of ABS / PVC / NBR alloys. The results show that various changes in ABS / PVC / NBR alloy are accompanied by changes in energy, mass and dimension. Glass transition temperature is an important parameter to characterize the compatibility of plastic alloys. Thermal stability of the alloy depends on HCl removal process of PVC in the alloy system. TMA curve of ABS/PVC/NBR is divided into flat section, expansion section and softening section, in expansion section products will deform and lose practical va lue. Flat section belongs to the application scope, and softening section provides technical data and theoretical basis for determining the optimal process. ABS/PVC/NBR is a new type of polymer material, which is widely used for bags, automobile panels and other outer packaging pro...
