Filler-containing molding composition and process for its manufacture

摘要

In filler-containing molding compositions a very good compatibility between the hydrophilic filler and the hydrophobic polymer matrix is obtained by using as adhesion promotor alkali metal salts of alkyl or alkylene-sulfonic acids or alkyl sulfates, the derivatives thereof and the acids on which the salts are based. The flow properties of the molding compositions and the mechanical properties of the shaped articles made therefrom are improved.
