Abstract: A wood polymer composite additive includes at least one maleic anhydride grafted polymer coupling agent, a second coupling agent that is at least one of a silane and siloxane, at least one peroxide crosslinking agent; and an amine compound. A wood polymer composite includes the additive, a thermoplastic polymer and cellulosic material. A wood polymer composite article is formed by extruding the composite material.

Abstract: The present invention concerns a composition and method of using adipamides in polymer applications. The composition is a blend of multi-components comprising dicarboxylic acids and amines. Specifically, the composition comprises adipic acid and monoethanolamine. The composition can further comprise at least one of the following: amides, esters, antioxidants, waxes, metal soaps, copolymers, polyesters, or fillers. However, these components are not necessary, and the composition can be utilized without these components. The composition is typically prepared in a cold reactor, wherein nitrogen flow is started and the temperature is increased gradually to approximately 360° F. Further, the disclosed composition reduces viscosity in polymer products, aids in melt integrity and process extrusion and promotes better mold release than conventional additives.
