Effects of reactive terpolymer containing maleic anhydride on thermomechanical properties of poly(vinyl chloride) based multicomoonent blends

摘要

In the present paper, the effects of reactive terpolymer containing maleic anhydride on the thermomechanical properties of PVC were investigated. The thermomechanical behaviour of multicomponent blend based on poly(vinyl chloride) (PVC), PVC/maleic anhydride-stryrene-methyl metacrylate (MA-St-MMA)-pentyl maleat-styrene-methyl metacrylate(nPnMA-St-MMA) were studied using the TMA method. The MA-St-MMA terpolymer, a reactive copolymer, formed the compatible blends with PVC. Results indicated that the elastic properties of PVC could be controlled by the MA-St-MMA terpolymer.
