Coran and Patel [16] showed that the morphology of an NBR/PP blend could be controlled by adding block copolymers comprising compatibilizing segments of both polymers.

All thermal, viscoelastic and mechanical effects observed for the polymer/PRM mixtures and rubber/PP/ PRM blends indicate that several additives act as efficient agents, considerably, contributing to the improvement of the dispersion, homogenization and compatibility of the investigated blends.

Effect of Compatibility on the Foaming Behavior
The effects of the different compatibility of the PP/PC blends on the foamability are inconsistent with the mechanical properties. The improvement of compatibility is generally beneficial for the mechanical properties because it indicates an improved phase adhesion between the blend partners due to a reduction in the interfacial tension and coalescence.

Effects of compatibility on foaming behavior
Polypropylene (PP) exhibits poor foaming property because of its low melt strength arising from its linear chains and relatively narrow molecular weight distribution. To fabricate a PP foam without cross-linking, PP should be blended with polyolefin elastomers (POEs) using chemical blowing agents.

The study of compatibility of polyethylene
The modification of the compatibility between polyethylene (PE) and polypropylene (PP) by using irradiated PE wax (PE wax) is the purpose of this study. In this part, polymer blends based on various ratios of PE and PP were blended with 2.5% PE wax in all the blend ratios to determine the optimum ratio of the blend to be compatabilized.
