Abstract
A cellulosic inclusion-thermoplastic composition that includes cellulosic inclusions and a thermoplastic polyolefin that forms a matrix in which the cellulosic inclusions are dispersed. A maleated polymer and a polar thermoplastic polymer resin of a polyamide or polyester are provided to improve adhesion between the cellulosic inclusions and the thermoplastic polyolefin. The polar thermoplastic polymer resin is characterized by a melting temperature greater than that of the thermoplastic polyolefin. The composition as provided has increased break tensile strength relative to a composition devoid of the polar thermoplastic polymer resin but otherwise is unchanged. The break tensile is measured at 23° Celsius and at an elongation rate of 50 millimeters per minute.
