OPTICAL AND ELECTRON MICROSCOPIC MICROSCOPE OBSERVATION ON EPDM-CR POLYBLENDS
乙丙-氯丁共混胶的光学及电子显微镜观察

The microstructure of EPDM-CR polyblends was investigated with electron and phase-contrast microscope. It was shown that the relative affinity of EPDM and CR for carbon blacks is different.By Comparing the structure of network domains, we found that carbon black displacement can occur in EPDM-CR polyblends systems. Structure of non-homogeneity domains is dependent upon the blending method and the carbon black content.
