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.

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.
