Wood-polyethylene composites using ethylene-vinyl alcohol copolymer as adhesion promoter.

Saw dust-reinforced linear low density polyethylene (LLDPE) (1:1) composites were prepared by using ethylene-vinyl alcohol copolymer (EVAL) as adhesion promoter to improve mechanical strength. To evaluate the optimum vinylalcohol (VA) content in EVAL, various EVAL samples containing different contents of VA were used. The tensile properties of saw dust-LLDPE composites were improved by using EVAL as adhesion promoter in place of ethylene-vinyl acetate copolymer (EVAc).
