The melt flow characteristics of blends of PVC and a copolymer of vinyl chloride and cetyl vinyl either were measured by means of a flow tester, and compared with those of PVC homo-polymer, Iightly plasticized PVC and other rigid PVC compositions. The apparent melt viscosity v. of the blends was less dependent on temperature, in contrast to other polymers. In the blends containing 25 to 75% of copolymer, there was no change in flow activation energy. The results of microscopic observation and dynamic loss measurement of the fabricated pro-ducts showed that the blends had rather two-phase structure than perfectly compatible phase. From these results, it was considered that the copolymer in the blends covered the surface of fiow unit of compatible mix of PVC and the copolymer in the course of processing.
