▎ 摘　　要

NOVELTY - Additive system comprises: at least one maleic anhydride grafted polymer coupling agent; at least one second coupling agent chosen from silane and siloxane; at least one peroxide crosslinking agent; and an amine compound. USE - The additive system is used for wood polymer composites for a formed article (all claimed). The composite is used to replace traditional wood products including building materials such as doors, frames, and window casings, and for exterior applications such as decking, and fencing. The composite is used for producing plastic products such as wood polymer composites, automobile, indoor/outdoor applications, filled compounds, wire/cable, fiber, any plastic application where reinforcement/enhancing physical properties is needed. ADVANTAGE - The composite has the advantages over all-wood products, such as flame resistance, resistance to rot and insect attack and deterioration due to the effects of moisture and UV light. The composite utilizes amine compounds as additives to improve physical properties of wood polymer composites, and utilizes additives to improve flex properties of wood polymer composite, preferably modulus of rupture (MOR). The composite utilizes additives for enhancing physical properties of the plastic products. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a wood polymer composite comprising at least one thermoplastic polymer, a cellulosic fiber material, and the above-mentioned additive system; (2) a formed article comprising the wood polymer composite; and (3) a method of making a wood polymer composite article, comprising providing the above-mentioned additive system, melt mixing a cellulosic material, at least one thermoplastic polymeric material and the additive system at a temperature sufficient to flow the thermoplastic polymeric material, and extruding through a die the wood polymer composite.
