The plasticizer effect of poly(propylene carbonate) (PPC) on glass transition temperatures of po1y(vinyl chloride) (PVC) has been investigated and compared with dioctyl phthalate (DOP), a common plasticizer of PVC. The decrease in glass transition temperatures of the PPC blended PVC was not significant when compared with that of DOP. For the theoretical calculation of solubility parameters group molar attraction constants have been employed. The PPC performance was within an acceptable range for some type of application.
