Abstract: A process for the preparation of filler-containing thermoplastic moulding compositions by mixing fillers with thermoplastics in the melt, where a) the fillers are mixed in a mixing device in the melt with a low-molecular-weight thermoplastic having a maximum melt viscosity of 30 Pas (measured at a temperature of 20 DEG C above the melting point of the thermoplastic and at a shear gradient of 1 000 s ), b) the resultant product is discharged from the mixing device, cooled and comminuted, and c) the comminuted product in the solid phase is subsequently subjected to post-condensation.

Abstract: A method for the production of polyamides by polymerization involves being carried out in the presence of water followed by granulation and post-polymerization, in which the monomers are polymerized at a water vapor pressure (p1) of at least 3 bar and the polymer melt is taken off in presence of a liquid, cooled and granulated at a hydraulic pressure (p2) of at least 3 bar. Independent claims are also included for: (1) polyamides obtained by this method; and (2) molded products, film, fibres and foam made from these polyamides.

Abstract: O.Z. 0050/42919 In a process for producing filler-containing thermoplastic molding compositions by mixing fillers with thermoplastics in the melt, a) the fillers are mixed in a mixing apparatus in the melt with a low molecular weight thermoplastic having a melt viscosity of at most 30 Pas (measured at 20.degree.C above the melting point of the thermoplastic compound and at a shear gradient of 1,000 s-1), b) the product thus obtained is removed from the mixing apparatus, cooled and comminuted, and c) the comminuted product is then subjected in the solid phase to a post-condensation.
