Abstract
This piece of work has investigated features of deformation of polyvinyl chloride (PVC) and polyethylene (PE) polymer blends, resulted in the presence of two types of compatibilizers, and made a comparative assessment of the elastic strength characteristics of the blends versus their variations produced in the intensity of mixing components in the melt. The effect of plasticization of PVC with dioctyl phthalate was found at increased speed of stirring, expressed by a decrease in the modulus of elasticity and stress at the yield point. For mixtures with a PVC matrix in the absence of a compatibilizer, an increase in the PE content leads to a drop in stress at the yield point and elongation at break; for equal mixture compositions with intense mixing, the deformation curves show a combination of the yield zone and orientational ordering.
