    Abstract: The invention relates to a process for the preparation of reinforced, impact-modified thermoplastic molding compositions which contain, based on 100 parts by weight, A) from 30 to 93 parts by weight of one or more thermoplastics from the group comprising the polyamides, polyesters, polycarbonates and polyphenylene ethers, B) from 5 to 50 parts by weight of fibers, preferably glass fibers, and C) from 2 to 20 parts by weight of one or more impact-modifying rubbers, in which process the fibers (B) are first introduced into the melt of the thermoplastic (A), components (A) and (B) are mixed, the rubber (C) is then introduced into the resultant mixture in the melt, and the resultant molding composition is extruded and granulated, wherein the reaction is carried out in one step, expediently at a constant temperature in the range of, advantageously, from 250 DEG to 300 DEG C.

    Abstract: The prodn. of high-mol. wt. polyamides from nitriles comprises (a) polymerisation of amino-nitriles of formula H2N(CH2)mCN (I) or mixts. of diamines (II) with dinitriles (III) in a mole ratio of (0.98:1)-(1.02:1) to give a prepolymer (A) with a rel. viscosity (1% in conc. H2SO4 at 23 deg.C) of 1.4-2.0: H2N-(CH2)m-CN (I) H2N-(CH2)n-NH2 (II) NC-(CH2)q-CN (III) m, n, p = 2-12; followed by (b) granulation and (c) solid-phase post-condensation at 5-100 deg.C below the m.pt. of the prepolymer in presence of an inert gas contg. at least 50 vol.% superheated steam, to give a high-mol. wt. polyamide (B) with a rel. viscosity of 2.3-5.0, the difference between the rel. viscosities of (A) and (B) being at least 0.4. Also claimed are (i) high-mol. wt. polyamides (B) as obtd. by this process; (ii) mouldings, film and fibres produced from these polyamides.
