| Abstract | ||||
| To improve the Vicat Softening Point of PVC compounds, blending technique was used to blend PVC with other polymers such as Acrylonitrile butadiene styrene (ABS), Acrylonitrile styrene acrylate (ASA) and Poly (methyl methacrylate) (PMMA) at different ratios (5, 10 and 20 %), then comparing the mechanical and thermal properties obtained with commercial heat modifier polymer Alpha Methyl Styrene-Acrylonitrile copolymer (AMSAN) The blended PVC mixtures were studied to find that, the best polymer that can be used to improve the Vicat Softening point. It was the blend of PVC with PMMA. Also, the effect of adding inorganic fillers to PVC mixtures such as Calcium Carbonate and Talc with different particles size at different amounts (5, 10 and 20 phr) were mechanically and thermally studied to find that, the suitable type of filler which can be used in enhancing the Vicat softening point, where it was Talc with particles size 0.7 Micron. By preparing the two best results achieved with PVC mixture which include PMMA and 0.7 Micron Talc it was obtained the highest Vicat softening point (VSP). It reached to 80.6 oC where it was 70.5 oC for the PVC without VSP improver and reached to 77.1 oC using commercial VSP improver. | ||||
