Composition， polymer composite article formed using same， and method of making same

Compositions and methods for making polymer composite articles. The composition comprises (A) filler in an amount of 10 to 90 wt%. The composition also comprises a polymer (B) in an amount of 10 to 90 wt %， and the polymer (B) comprises polyvinyl. In addition， the composition comprises (C) organopolysiloxane in an amount of greater than 0 to 10 wt%; The (C) organopolysiloxane has at least one silicon-bonded hydroxyl group and has a viscosity of 1，000 to 60，000 mPa·s at 25°C. The range of components (A) to (C) is based on the total weight of components (A)， (B) and (C) in the composition. A composition and a method for preparing a polymer composite article.
