Abstract: A multilayer, biaxially stretched and thermofixed tubular film (I) is formed of (A) an inner layer consisting of a thermoplastic polyamide (C) a core layer consisting of a styrene-butadiene block copolymer and (D) an outer layer consisting of a thermoplastic polyamide. Independent claims are included for (i) a process for the production of (I) by stretching the primary film by at least 1.5 times in the length and transverse directions followed by thermal fixing and (ii) a sausage skin prepared from (I).

Abstract: The invention relates to microporous films obtained by mixing A) 55 to 99.9 wt. % thermoplastic polyamides with B) 0.1 to 10 wt. % of a salt having a solubility in water of > 5 g/100 ml at 80 DEG C and optionally C) 0 to 30 wt. % further additives, whereby the sum of the weight percentages of constituents A) to C) equals 100 %. The invention also concerns the production of a film using standard flat sheet extrusion or blown film methods and subsequent aqueous extraction of constituents B).

Abstract: The invention concerns the use of homo- or copolymers A as branching agents for thermoplastic polymers containing amino groups. The homo- or copolymers A are composed of: A1) between 40 and 100 wt.% monomers of general formula (I); A2) between 0 and 60 wt.% of monomers of general formula (II); and A3) between 0 and 10 wt.% of further radically polymerizable monomers, the weight percentages of monomers A1) to A3) totalling 100 % and the substituents having the following meanings: R , R , which may be identical or different, designate the rests hydrogen or C1-C4 alkyl; R , R , R , R , which may be identical or different, designate the rests hydrogen or C1-C4 alkyl, provided that at least two rests from the group R , R , R and the group R , R , R are hydrogen; and R designates an alkyl, cycloalkyl, aryl or aralkyl rest.

Abstract: Production of a polymer based on a dicarboxylic acid and a diamine by polycondensation in an extruder, by (a) heating a mixture which is solid at room temperature of a dicarboxylic acid with 4 to 12 C atoms and a diamine with 4 to 12 C atoms with a residual humidity content of under 5 wt.% in a counterflow double-worm extruder to a temperature in the region of 150 to 400 DEG C under autogenous pressure to produce an extract A, (b) taking the extract A to a synchronous double-worm extruder, in which the extract A is exposed to a temperature in the 150 to 400 DEG C range and any residual water and water from polycondensation is removed via outgassing apertures, to obtain an extract B, provided that the synchronous double-worm extruder comprises at least two segments with different pressures.
