    Research output: Patent


    The present invention is directed to compositions comprising (a) a synthetic polymer, (b) a talc as a filler, wherein the talc particles have a mean particle size of from 0.4 to 25 µm, and are present in an amount of from 0.1 to 10 % based on the weight of component (a) and (c) a dispersing agent which is based on a non-ionic surfactant or an amphiphilic statistical, block or comb copolymer; provided that when the synthetic polymer (a) is a polyamide, this is present in an amount of less than 55 % based on the weight of (a), (b) and (c).
