Mechanical and rheological properties of poly(ethylene adipate) (PEA)/low‐density polyethylene (LDPE) blends were investigated. DSC results showed that there is no miscibility between PEA and LDPE. Tensile strength decreases with increasing PEA content, while the modulus increases. Elongation at break decreases with increasing PEA content. A rheological constitutive equation was used for describing and predicting the steady‐state shear viscosity of PEA/LDPE blend. The suggested equation was successfully able to describe and predict viscosity of the blend as functions of shear rate and temperature. © 1997 John Wiley & Sons, Inc.
