In this work, a new hyperbranched polyester polymer (HBP) was prepared by using A2+B3 polycondensation polymerization methodology and blended with polypropylene PP. Both Nuclear magnetic resonance (NMR) and Fourier transform spectroscopy (FTIR) were used to characterize the HBP. The prepared HBP was blended with polypropylene (PP) in different weight compositions in order to study the effect of the addition of HBP on the polypropylene mechanical and thermal properties. A twin-screw extruder was used for the preparation of the polymeric blends (PP/HBP) and samples were manufactured using different blend compositions (5%, 10%, 20%) wt. Tensile test, impact test, density, hardness, and differential scanning calorimetry (DSC) were conducted to assess the blend properties. Results show that the blend properties and material characteristics were improved with the addition of the HBP. However, the tensile properties were decreased with the addition of HBP due to the immiscibility and different polarity of PP and HBP.
