Methyl acrylate (MA) monomer was graft copolymerized onto Hibiscus sabdariffa stem fiber and used to explore the additive effect of vinyl acrylate (VA) and ethyl acrylate (EA) on percentage grafting and the properties of the fiber, in binary vinyl monomeric mixtures. The graft copolymers were reinforced into phenol-formaldehyde polymer matrix to form biocomposites and characterized by FTIR, XRD, TGA, DTA, and SEM techniques. They were evaluated for physico-chemical changes in properties like moisture absorption at different relative humidity levels and chemical resistance against 1 N NaOH and 1 N HCl. These graft copolymers-reinforced biocomposites had higher mechanical strength like hardness, modulus of rupture, modulus of elasticity, and stress at the limit of proportionality. These novel materials can have numerous scientific and industrial applications for the development of technology.
