    Abstract: A thermoplastic polymer mixture comprising m polymers Pn, where m is a natural number greater than 1 and n is a natural number from 1 to m, where n is a natural number from 1 to m, where each of the polymers has one or more functional groups of the structure -(R )x-C(O)-(R )y- present as repeat units in the main chain of polymer Pn where x and y, independently of one another, are 0 or 1, and x+y=1 R and R , independently of one another, are oxygen or nitrogen bonded into the main polymer chain, where in the differential distribution curve W(M) determined to DIN 55672-2 in hexafluoroisopropanol as eluent the polymer mixture has at least two maxima of the relative frequency W, and after aging of the polymer mixture at the melting point of the polymer mixture determined to ISO 11357-1 and 11357-3 for 5 minutes, the polymer mixture has in the differential distribution curve W(M) determined to DIN 55672-2 in hexafluoroisopropanol as eluent at least 2 maxima of the relative frequency W, and the position of the maxima here after aging of the polymer mixture at the melting point of the polymer mixture is within three times the recurrent standard deviation sigma(r) of MP in percentage of the value measured to DIN 55672-2, based on the position of the maxima prior to aging of the polymer mixture at the melting point of the polymer mixture.

    Abstract: A thermoplastic polymer mixture (I) containing a polyamide (II) and a polymer (III), where the melt viscosity, as measured at 280 deg C is 100-20,000 s-1 is at most 75% of the melt viscosity measured in accordance with ISO 1443 of polyamide (II) at 280 deg C, and the boundary surface tension between a melt of polyamide (II) and a melt of polyamide (III) at 280 deg C, measured in accordance with US patent 5,50,607 by the Spinning-Drop-Method is in the region of 0-10 mN/m. A thermoplastic polymer mixture (I) containing (wt.%): (a) a polyamide (II)(50-99.9), (b) a polymer (III)( 0.1-50), where the melt viscosity, as measured in accordance with ISO 1443 of polyamide (II) at 280 deg C over the whole Scherraten (sic) region is 100-20,000 s-1 is at most 75% of the melt viscosity measured in accordance with ISO 1443 of polyamide (II) at 280 deg C, and the boundary surface tension between a melt of polyamide (II) and a melt of polyamide (III) at 280 deg C, measured in accordance with US patent 5,50,607 by the Spinning-Drop-Method is in the region of 0-10 mN/m. Independent claims are included for: (1) a process for preparation of a fiber by spinning a melt of a thermoplastic polymer, using the above polymer mixture (I) as the thermoplastic polymer; (2) a fiber obtained by the above process; (3) a carpet containing the above fiber; and (4) flat structure textiles containing the above fiber.
