The study demonstrates improved compatibility in EPDM and CPE blends, highlighting solvent blending's potential without compatibilizers.
The study on the development of compatible polymer blends, specifically Ethylene Propylene Diene Terpolymer (EPDM) and Chlorinated Polyethylene (CPE), is challenging due to their differing polarities. Typically, compatibilizing agents are required to achieve a homogeneous blend between the non-polar EPDM and polar CPE. In this work, we successfully prepared EPDM/CPE blends using a solvent blending method without the need for compatibilizers. The resulting blends exhibited excellent compatibility, as confirmed by Scanning Electron Microscope (SEM) images, highlighting the potential of solvent blending in overcoming polarity differences between polymers.
