Abstract:
The preparation of blend of sulfonated polystyrene (sPS) and maleated natural rubber (MNR) using the Polyethylene-graft-maleicanhydride (PE-g-MA) as compatibilished has been done. The blending process was done in dilute solution in each polymer, followed a steam and casting process at particular temperatures. The composition of sPS and MNR was varied at 1:9; 2:8; 4:6 and 6:4 (w/w). The characterization of membrane blend of sPS-MNR/PE-g-MA properties was determined by using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The data showed that the homogeneity and the crystallinity of membrane were affected by the composition and process condition. The XRD data show that the Membrane (sPS-MNR / PE-g-MA) with sPS: MNR ratio 2:8 produces diffraction patterns with higher intensity and SEM images showed that membrane has a better homogeneous surface morphology than the others.
