ABSTRACT: In this paper morphological transformation of sisal fiber by graft copolymerization with methyl acrylate and its binary mixture with acrylic acid (AAc), vinyl acetate (VA) and n-butyl acrylate (BuA), using FAS-KPS initiator, under influence of microwave radiations has been reported. Optimum reaction conditions for maximum graft yield were kept same as that in case of grafting of principal monomer. Maximum grafting has been observed in case of sisal-g-poly(MA+VA). The Graft copolymers thus formed were characterized with SEM, TGA and XRD techniques. Thermal stability has been found to increase and percentage crystallinity and crystallinity index decrease upon grafting.
