The blending effect of poly(vinyl chloride) with relatively higher molecular weight (HMW‐PVC) and relatively lower molecular weight (LMW‐PVC) has been investigated by measuring various mechanical properties: melt properties, tensile strength, tensile modulus, and impact strength. The blended PVC has slightly improved melt properties in comparison with the HMW‐PVC used. The tensile strength of the blended PVC is related to the weight‐average polymerization degree ( P ω) of LMW‐PVC and the LMW‐PVC content. At the LMW‐PVC content of 20%, the tensile strength of blended PVC is a maximum: approximately 58 MPa. © 1993 John Wiley & Sons, Inc.
