Abstract: This invention relates to a brush containing mono-filaments containing a polyamide which comprises polyamide-410. Preferably, the brush is a toothbrush.

Abstract: Process for manufacturing a laminate includes the application of a layer of polyamide to a substrate. The polyamide used is mainly branched polyamide that is at least composed of units derived from AB monomers that a) have both a carboxylic acid group and an amine group; b) at least one compound I, being a carboxylic acid (Av) with functionality v?2 or an amine (Bw) with functionality w?2; c) at least one compound II, being a carboxylic acid (Av) with functionality v?3 or an amine (Bw) with functionality w?3, with compound II being a carboxylic acid if compound I is an amine, or with compound II being an amine if compound I is a carboxylic acid. The substrate may be (metallized) paper or paperboard so that a laminate is formed which is very suitable for manufacturing packaging for foodstuffs.

Abstract: A process for producing a multilayer flat film containing a polyamide layer and a layer of another polymer. The polyamide layer is essentially formed from an intrinsically gel-free, randomly branched polyamide including units derived from: AB monomer possessing both a carboxylic acid group (A) and an amine group (B), at least one compound I, being a carboxylic acid (Av), with functionality v?2 or an amine (Bw) with functionality w?2, and at least one compound II, being a carboxylic acid (Av) with functionality v?3 or an amine (Bw) with functionality w?3. When compound II is a carboxylic acid compound I is an amine. When compound II is an amine compound I is a carboxylic acid. The polyamide layer and the layer of the other polymer are adjacent to each other.

Abstract: A multilayer film is produced by blow-moulding a multi-layer film containing at least a polyamide layer and a polyolefin layer. The polyamide layer includes a branched polyamide.

Abstract: An impact-resistant polymer composition exhibiting improved impact resistance at no loss in creep is obtained by melt-mixing a solid matrix polymer A with a solid composition containing the rubber composition dispersed in a matrix polymer B. The dispersion of rubber composition in matrix polymer B is obtained by melt mixing the matrix polymer B with a rubber composition which includes a functionality rubber and a non-functionality rubber. The amounts of the components are such that the impact-resistant polymer composition contains 0.5 to 75 parts by weight of the rubber composition per 100 parts by weight of the matrix polymers A and B. The composition may be used in various applications, including plugs, heat bridges for aluminum windows, hammer heads and the like.

Abstract: The invention relates to a process for the preparation of an impact-resistant polymer composition comprising 0.

Abstract: A composite elongated-shaped product is made from two or more synthetic polymer components. The product may be a split-fiber, thread, film or a ribbon-shaped one. One of the polymer components is polypropylene which forms more than 50 percent by weight of the product. At least one other polymer component is distributed in the polypropylene. The composite product contains 65 to 95 percent by weight of polypropylene and 35 to 5 percent by weight of one or more polyesters and/or polyamides. The polyesters are built up of structural units derived from one or more dicarboxylic acids, at least 70 mole % of which are from terephthalic acid. Other structural units are derived from one or more low-molecular weight diols, at least 70 mole % of which are from a diol having the formula HO(CH.sub.2).sub.n OH, where n is a whole number and may be 2, 4 or 6. The polyamides are formed by polycondensation of caprolactam or adipic acid and hexamethylene-1,6-diamine.
