    Abstract: The invention concerns multilayered biaxially stretched and thermoset tubular films composed of an inner layer (A) comprising at least one thermoplastic copolyamide as an essential component, at least one intermediate layer (B) which is composed of a polyolefin homo- or copolymer, and an outer layer (C) which is composed of at least one thermoplastic polyamide as an essential component. The tubular films are characterized in that the layer thickness ratio of (C) : (A) is between 5 : 1 and 2 : 1.

    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.
