Abstract
The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degredation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.
