1% IIe@TRHbIX 6HTYMOB (305-310°C). -4ncvendung einiger erdolchemischer Produkte als Plastifikatoren fur PolyvinylchloridEs wird die plastifizierende Wirkung von Extrakten niedrig-, mittel-und hochsiedender Erdoldestillate auf PVC untersucht. Mit steigender Konzentration nehmen die Glas-und die FlieStemperatur des Polymers ca. um 20 bis 25 K ab, wHhrend sich die ReiRfestigkeit nur geringfiigig andert. Erdolbitumen erhoht die Glastemperatur des PVC. DTA-und TG-Untersuchungen ergeben eine Verschiebung der endothermen Effekte des thermischen PVC-Abbaus von 278 "C nach hoheren Temperaturen, was am ausgepragtesten im Falle der hochsiedenden Fraktionen (295 "C) und des Bitumens (305 bis 310°C) ist. dpplication of petrochemical products as plasticizers for poly(oiny1 chloride)The plasticizing effect of extracts based on petrol destillates with low, medium and high viscosity on PVC was investigated. Increasing their concentration from 5 to 20% the values of T, and T, of the polymer decrease by about 20 to 25 K. The tensile strength variation was not significant. Petrol bituminous products bead to higher T, of PVC. DTA and TG plots show a shift of thermal destruction on endothermic effects (278°C) to higher temperatures. This was more emphasized with high viscosity extracts (295°C) and petrol bituminous products (305 to 310°C).
