    Abstract: Optical cable has a fiber core (1) and fiber cladding (2) adhered with inner and outer external layers (3,4) respectively comprising molding compositions (A and B) having polyamides (I,II). (A) has zero-shear viscosity of 400-6000 Pas at 220 degreesC. (B) further contains flame retardant and impact modifier. Amount of polyamide (II) (a), flame retardant (b) and impact modifier (c) is based on total amount of (a,b,c). An optical cable comprises a polymer optical conductor comprising a fiber core (1) and a single layer or multi-layer fiber cladding (2) which is adhered with inner external layer (3) with a peel force of at least 50 N and an outer external layer (4) adhered to inner external layer with peel force of 30N or less. The inner and outer external layers respectively comprise molding compositions (A and B) containing polyamides (I,II). Polyamide (I) is selected from PA 11, PA 12, PA 1012, PA 1212, copolyamide of at least 2 of PA 11, PA 12, PA 1012, PA 1212 containing not more than 30 mol% of comonomer, and their mixtures, and contains at least 50 micro-eq/g of amino end groups. Composition (A) has zero-shear viscosity of 400-6000 Pas according to ASTM D 4440 at 220 degreesC. The polyamide (II) is selected from PA 11, PA 12, PA 1012, PA 1212, copolyamide of at least 2 of PA 11, PA 12, PA 1012, PA 1212 containing not more than 30 mol% of comonomer, polyetheramide of the above polymers, and their mixtures. Composition (B) further contains 5-45 wt.% of a flame retardant and 0-60 wt.% of an impact modifier. The amount of polyamide (II), flame retardant and impact modifier is based on total amount of polyamide (II), flame retardant and impact modifier.

    Abstract: A molding composition comprises (wt.%): (A) a polyetheramide (99.9-95) based on a linear 6-12C aliphatic diamine, a linear 6-12C aliphatic or aromatic dicarboxylic acid and a primary amine-terminated polyetherdiamine with at least3C per ether oxygen atom; and (B) a copolymer (0.1-5) containing acid anhydride or epoxide units (0.8-20). A molding composition comprises (wt.%): (A) a polyetheramide (99.9-95) based on a linear 6-12C aliphatic diamine, a linear 6-12C aliphatic or aromatic dicarboxylic acid and a primary amine-terminated polyetherdiamine with at least3C per ether oxygen atom; and (B) a copolymer (0.1-5) containing: (i) acrylate units of formula (I) (0-85); (ii) imide units of formula (II) (0-80); (iii) acrylic acid units of formula (III) (0-15); (iv) acid anhydride or epoxide units of formula (IVA) or (IVB) respectively (0.8-20); and (v) 0-95% hydrocarbon units of formula (V) (0-95). Alkyl = 1-6C alkyl; R1 - R7 = H, CnH2n+1 or phenyl; m = 0 or 1; and n = 1-6.

    Abstract: The thermoplastic composite material comprises a polyamide layer bonded to a polyester layer by means of an adhesive (I) comprising a blend of polyamide prepared from stoichiometric amounts of a diamine containing 6-12C atoms and dicarboxylic acids, and a polyester prepared from a diol containing a mixture of dicarboxylic acids. Thermoplastic composite material comprises a polyamide layer bonded to a polyester layer by means of an adhesive (I) comprising at least 50 wt.% of a blend of: (a) 20-80 wt.% of a polyamide prepared from stoichiometric amounts of a diamine containing 6-12C atoms and dicarboxylic acids, including at least 5 mol% of dicarboxylic acids (II) containing 10-36 C atoms; and (b) 20-80 wt.% of a polyester prepared from a diol containing 2-12 C atoms and a mixture of 30-95 mol% of an aromatic dicarboxylic acid containing 6-20 C atoms and 5-70 mol% (II). Independent claims are also included for the following: (1) production of the composite material by multicomponent injection molding, coextrusion or coextrusion/blow molding; (2) an adhesive as defined for (I).
