1. A composition for preparing a polymer composite article, the composition consisting of:
(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, and wherein the (B) polymer is not functionalized to react with component (C);
(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 mPa·s at 25° C.; and
optionally one or more of (D) a compatibilizer, (E) a colorant, (F) a blowing agent, (G) a UV stabilizer, (H) an antioxidant, (I) a process aid, (J) a preservative, (K) a biocide, (L) a flame retardant, and (M) an impact modifier;
each based on the total weight of components (A), (B) and (C) in the composition.
