摘要：

Binary blends of poly(vinyl chloride) (PVC) and poly(vinyl butyral) (PVB) have been prepared by solution blending. The physical and mechanical properties of the blends are studied usind differential scanning calorimetry (DSC), thermogravimetry (TG) and tensile testing. The DSC results showed a high degree of molecular mixing of the two polymers. All the blends exhibited one major glass transition temperature (T-g) whose position on the temperature scale is lowered with increasing level of PVB. The thermal stability of the blends was found to increase with the increase in the PVB content in the blend. This is illustrated by both TG and rate of thermal dehydrochlorination of various investigated blends. (C) 1999 Elsevier Science Ltd. All rights reserved.
