Abstract (en)
[origin: US2005121817A1] A continuous process for the preparation of a thermoplastic molding composition is disclosed. Accordingly a first stream containing a molten polymer and at least one additive is introduced into a second extruded stream that contains a molten polymer to produce a combined stream. The temperature of the first stream that is below that of the second stream. The additive is in either liquid form, in solution or in dispersion.
