The standard method for DRC determination involves drying of the sheeted coagulum in a conventional oven at 70°C for about 12 hours. This lengthy drying procedure can be replaced by microwave drying which is fast, uniform and with comparable accuracy. In this paper the performance of this technique will be shown particulary the effect of microwave power and initial mass of the latex to the final drying time. By using the water load technique for microwave power level determination, the optimum drying time is proposed for a specific mass of latex. The experimental results show that the final drying time for 10 g of initial mass of fresh latex and at a power level of about 743 watt is less than 10 minutes. There is not much difference in final drying time for samples with initial mass between 5-30g.
