To understand the changes in mechanical properties, both morphology of injection molded samples and recycled granulates were investigated. A three-phase morphological model was applied for the evaluation of morphological properties while mechanical properties were determined by tensile and impact tests. Relationship was found between morphological and mechanical characteristics as a function of time elapsed since production. Crystalline ratio, tensile strength, and modulus of injection molded specimens increased while impact strength decreased in the four weeks after production.
