Abstract
Grafting of poly(ethyl acrylate) and its copolymers was carried out on peroxide-treated sisal fibers. Effect of reaction conditions on graft parameters like rate of graft copolymerization and % grafting were studied. The kinetics of graft copolymerization of ethyl acrylate onto peroxide-treated sisal fibers was studied, and the rate expression for the graft copolymerization was found to be Rg = k[EA]1.74[FAS]0.51. Grafting of poly(EA) and copolymers onto peroxide-treated sisal fibers was confirmed by FT-IR spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction studies. Thermal stability and percentage crystallinity of sisal fibers were enhanced with peroxide treatment and graft copolymerization.
