Like alloys in metallurgy, polymers are blended to obtain new characteristics, which is important to extend their application area. In this study, three different compositions of azide-functionalized poly(vinyl chloride)-PVC-N3 and poly(ε-caprolactone)-PCL were blended. Physical properties, such as mechanical and thermal behavior of the blends, were investigated through the tensile test, DSC, and TGA. Also, a blended polymer with equal participation of each constituent was trained to determine the shape memory behavior of the sample. The results showed that PVC-N3 and PCL were completely miscible; therefore, all physical properties are somewhere between the pure polymers. The blend with only 50% PCL, as an example, still kept its shape memory behavior; additionally, the blended polymers partially achieved crystalline behavior by adding PCL to the PVC-N3. The tensile test also showed that the modulus of toughness and other mechanical behavior depends on the compositional ratio of the polymers. Consequently, the miscibility of the PCL and PVC-N3 enhances the physical properties of both polymers as a function of composition.
