    Abstract: Silanes grafted onto celluloses and lignocelluloses' fibers, in presence of free radical initiator, reinforced thermoplastic composites, which replace the inorganic fillers. Polyethylene composites are prepared by a hot melt mixing process, wherein the cellulosic molecules graft with silanes, and part of the thermoplastic polymer, can be initiated to attach with the maleic anhydride present. The grafted cellulose molecules with aminosilanes combine easily and strongly with that maleiated polymer to give the superior composite properties. The silanes grafted onto organic fillers proved to be higher in energy, secant modulus, tensile strength and strain compared to inorganic fillers such as glass fibers or mica composites. Noting that the cost of silanes grafted onto cellulosic or lignocellulosic fibers are several times lower than that of treated glass fibers or mica.

    Abstract: Polymer composites can be made from cellulosic & polymeric matrix, which may be thermoplastic or thermosetting, or rubber. The cellulosic material is grafted with isocyanate bonding agent and may be mixed with prebonded inorganic filler with a bonding agent. Furthermore, said bonded inorganic filler can be added to polymer composites filled with cellulosic fibers grafted with silylating agent. These polymer composites are useful for most plastic articles.
