摘要： It has been found that the properties of poly(vinyl chloride) based polymers are substantially enhanced through the use of a specific plasticizer system. In particular, the use of specific triarylphosphates in combination with specific diarylphosphates in specific proportions not only plasticizes the PVC polymer but produces a transparent, flame retardant heat resistant, easily worked polymer. These materials are used so that the diarylphosphate is 30-45% of the total concentration of the phosphates and such that 45 to 70 parts of the phosphates are present per 100 parts of the polymer.
