Abstract
The effect of structural and physical inhomogeneity of a polymer blend on the thermal degradation of PVC in the presence of PMMA was studied . It was found that the rate of PVC degradation varied, depending on t he method of blending (coprecipitation from a common solvent, melt ble nding, solution mixing), The effects observed are related to changes i n the thermodynamic miscibility of components, phase state of the blen d, and degree of association of PVC and PMMA macromolecules in samples prepared using different methods and solvents.
