Mechanical degradation of polyvinylchliride (PVC) has been studied kinetically by using a vibration ball mill under one atmospheric pressure at room temperature. The degree of degradation was determined by the number-average chain length at various stages of mechanical degradation. The extent of degradation was represented by the rate constant of degradation (k_s) and the final average chain length (P_∞). The mechanical degradation of polycarbonate (PC) was also carried out at the same condition. In order to know the interaction between PVC and PC during mechanical degradation by a vibration ball mill, the mixtures of PVC and PC with various mixing ratios were also degraded with a vibration ball mill. k_s of PVC in the presence of PC increased with increasing amount of PVC, white k_s of PC decreased with increasing amount of PVC. These results were used to discuss the mechanical degradation behavior of polymer in a vibration ball mill.
