Abstract: Waxes and polymeric waxes can graft with a coupling agent by employing a radical process. The resulted grafted waxes can be applied:1. For Coating and bonding with surfaces of materials to be applied as water-proofing antirust and reinforcing fillers.2. As enhancing coupling agent to bond with plastics, rubber and asphalt.3. As adhesive materials.

Abstract: Composite materials based celluyloses grafted with titanium coupling agents reinforce polymeric resins, cement and gypsum. Processes for preparing said composites are disclosed.

Abstract: Composite materials based on cement or gypsum materials reinforced by mixing with cellulosic fibers grafted with silylating agents. Processes for preparing these reinforced composites are also disclosed.

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.

Abstract: Composite material based on a polymeric or copolymeric substance which may be a thermoplastic or thermosetting material or rubber, and an organic material which is cellulosic or starch. The cellulosic material is grafted with a silylating agent. Processes for preparing this composite are also disclosed.

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.
