Abstract:
A process is described for the modification of polymer melts by means of finely divided inorganic solid particles (melt modification process), in which a powdery additive which contains the inorganic solid particles with a maximum particle size of 1 μm embedded in finely divided form in a matrix of an organic substance, the organic substance containing one or more of the substances from the group consisting of polyols, polyglycols, polyethers, dicarboxylic acids and derivatives thereof, AH salt, caprolactam, paraffins, phosphoric acid esters, hydroxycarboxylic acid esters and cellulose, is incorporated into the polymer.
