Abstract
A method for determining the concentration of additives in a compounding process by measuring the capacitance and dissipation factor (tan.delta.) of the mixture and converting such values to the concentrations of the additives. This method may also be utilized to determine the concentration of the polymers in the mixture. This method is preferably applied to a compounding process of blending polyphenylene oxide and polystyrene thermoplastic resins and is preferably applied to a continuous compounding process of these resins to determine therein the concentration of an aryl phosphate ester flame retardant.
