ABSTRACT:
Glass fiber reinforced polycarbonate molding compositions are taught which have improved mechanical properties. This improvement is achieved by incorporating between about 0.5 to 5 wt.% of organopolysiloxanes into the composition. The compositions of this invention have improved impact, notched impact and elongation properties without a loss in elastic modulus.
