| Abstract: | Polycarbonate (PC) and acrylonitrile–EPDM (ethylene/propylene/diene elastomer)–styrene ter‐polymer (AES) blends and PC/AES/organically modified montmorillonite (OMMT) composites were prepared at 20%, 40%, 50% by weight of AES and 3% by weight of OMMT. The microstructure, interfacial interactions, and rheological properties of the PC/AES blends and PC/AES/OMMT composites were studied systematically. X‐ray diffractometer (XRD) results reveal that the AES is easier to intercalate into OMMT than PC, and the content of AES has a little effect on the interlayer distance of OMMT. Wetting coefficient calculation indicates that OMMT distributes primarily at the interface of the polymer blend. Field emission scanning electron microscope (FE‐SEM) observation indicates that the phase morphology of PC/AES blends and PC/AES/OMMT composites is not influenced by the OMMT. However, linear rheological properties suggest that the addition of OMMT has a great effect on the linear rheological property. |
