X-Ray Diffraction and Morphology Studies of Sulfonated Polystyrene and Maleated Natural Rubber Blend with PE-g-MA as Compatibilished

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
