【 摘 要 】

Problem statement: Poly (vinyl chloride) suffers from poor heat stability. The thermaldegradation of the polymer leads to the evolution of hydrogen chloride gas, extensive discoloration ofthe polymer and lowering of physical and mechanical properties. Approach: Binary blends of Poly(Vinyl Chloride) (PVC) and Poly (Glycidyl Methacrylate) (PGMA) have been prepared by solutionblending aimed at the improvement of thermal and mechanical properties. Results and Conclusion:Thermal properties of the blends were studied using Scanning Calorimetry (DSC), Thermogravimetry(TGA) and potentiometric rate of dehydrochlorination. The increase of the PGMA content in the blendleads to thermal stability of the blend as shown from the thermogravimetry and the rate ofdehydrochlorination results. All blends exhibited one major glass transition temperature (Tg) whoseposition on the temperature scale was lowered with increased level of PGMA. The miscibility ofblends was also confirmed by the use of Scanning Electron Microscope (SEM). The improvement ofthe mechanical properties of various blends of the two polymers was also obtained.
