Beschreibung
Zusammenfassung:	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. La présente invention concerne un additif de composite polymère-bois comprenant au moins un agent de couplage polymère greffé à l'anhydride maléique, un second agent de couplage qui est au moins l'un parmi un silane et un siloxane, au moins un agent de réticulation peroxyde ; et un composé amine. Un composite polymère-bois comprend l'additif, un polymère thermoplastique et un matériau cellulosique. Un article de composite polymère-bois est formé par extrusion du matériau composite.
