    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.

    Abstract: In a process for producing modified rubber moulding materials, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R stands for a hydrogen atom or a methyl group and R stands for an alkyl group with 1 to 32 carbon atoms, a first monomer (b) with two or more double bonds and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is dissolved into or swollen with a third or several other monomers (d), optionally with admixture of a solvent, and in a third step, the second mixture (C) obtained by dissolving or swelling is polymerised into the modified rubber moulding material (D).
