Abstract
AbstractAn investigation of butyl stearate, butyl oleate, butyl rieinoleate, and methyl lmoleate was made to determine the extent of their compatibility with poly(vinyl chloride) and their plasticizing effects on the physical, properties of the resulting molded sheets. These monoesters were evaluated as the sole plasticizer and in combination with DOP. The results showed the materials to have limited compatibility in general, being less than 10% of the total mix. In combination with DOP these compounds were found to improve the plasticizer efficiency, color, low temperature flexibility, and heat stability of the molded poly (vinyl chloride) sheets over those containing DOP as the sole plasticizer. Tensile strength, per cent elongation, and light stability properties were essentially comparable to those found for pure DOP.
