Download or read book Thermal Degradation of Polymer Blends Containing Poly(vinyl Chloride) written by David W. Lee and published by . This book was released on 1987 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The thermal degradation of blends of poly(vinyl chloride) (PVC) with poly(vinyl acetate) (PVA), and two ethylene-vinyl acetate copolymers containing 70 weight percent vinyl-acetate (EVA70) and 45 weight percent vinyl acetate (EVA45) were studied by thermogravimetric analysis and direct-pyrolysis mass spectrometry. The PVC, PVA, EVA45 and EVA70 degrade in two-step processes for each polymer. The PVA/PVC, EVA45/PVC and the EVA70/PVC blends do show some interaction during the first step of the degradation process while the respective second steps are unaffected. The acid produced by the degradation of one polymer causes accelerated loss of the other acid in the blend. The extent of the interaction is a function of the miscibility of the blends."--Abstract.
