<p>The present invention relates to a method of preparing a highly filled polymer composition such as a flame retardant or reinforced polymer composition wherein the polymer and the filler are chemically bonded to each other. The method comprises the step of i) mixing together filler, mono- or di-carboxylic acid or anhydride thereof, radical generator and thermoplastic polymer, under conditions where said at least one radical generator is not activated; ii) activating the radical generator to form a chemically bonding between di-carboxylic acid or anhydride thereof and polymer. The method is simple and economical acceptable, and results in a highly filled polymer composition which have good mechanical strength.</p> |
