Composition, polymer composite article formed therewith, and method of preparing same

A composition for preparing a polymer composite article, said composition comprising:

• (A) a filler in an amount of from 10 to 90 wt. %, wherein the (A) filler comprises a mineral filler, a glass fiber, a carbon fiber, or combinations thereof;
• (B) a polymer in an amount of from 10 to 90 wt. %, wherein the (B) polymer is selected from polyolefins, polyamides, polyesters, polycarbonates, or combinations thereof;
• (C) an organopolysiloxane in an amount of from greater than 0 to 10 wt. %;
• the (C) organopolysiloxane having at least one silicon-bonded hydroxyl group and a viscosity of from 1,000 to 60,000 m·Pas at 25° C.;
• each based on the total weight of components (A), (B) and (C) in said composition;
• and
• (D) a compatibilizer comprising silane grafted polyethylene, maleic anhydride grafted polyethylene, and/or maleic anhydride grafted polypropylene.
