Abstract
This work reports on the preparation of natural fibre copolymers by the grafting of hydrophobic monomer, methyl methacrylate onto chemically modified pineapple leaf fibre using a complex initiating system. The modified pineapple leaf fibre-g-PMMA copolymers so obtained were characterized by FTIR, their thermal behaviour by TGA, and their morphology by scanning electron microscopy. In addition, their tensile strength, elongation and tenacity were measured. The extent of water absorption by the grafted PALF, showed that the grafting of MMA imparts hydrophobicity onto PALFs. Biodegradation of the copolymers was evaluated in sludge water and soil and by using cultured microorganisms. 17 refs.
