    摘要: The invention relates to injected components based on polyamide resin (A) and on at least one copolymer (B) of ethylene and of an unsaturated epoxide, the copolymer (B) being obtained by copolymerization or by grafting the epoxide. The copolymer (B) is advantageously an ethylene/alkyl (meth)acrylate/glycidyl (meth)acrylate copolymer. The melt flow index of the compositions containing (A) and (B) is greater than the ratio of the melt flow index of (A) over 0.175 times the weight percentage of (B).

    摘要: The invention relates to a translucent and flexible polyamide-based composition, which is easy to process, in particular by extrusion, comprising: (A) from 50 weight-% to 95 weight-% 1) of at least one polyamide resin (I), 2) of various additives (IV) such as stabilizers, mould-release agents, lubricants, crystallization accelerators, pigments, organic and/or inorganic fillers or dyes, or antioxidizing agents, 3) optionally of at least one plasticizing agent (V), and (B) from 5 weight-% to 50 weight-%: (a) of at least one ethylene-alkyl (meth)acrylate-unsaturated dicarboxylic acid anhydride terpolymer (II), (b) of at least one ethylene-alkyl (meth)acrylate copolymer (III) with 1/30.ltoreq.(b)/(a).ltoreq.2. In accordance with the present invention, the flexural modulus of the composition, measured according to ISO standard 178, is less than or equal to 2/3 of the flexural modulus of the PA resin (I) alone and is strictly less than 750 MPa. This composition has good extrudability and can be used to make many articles, in particular pipes.

    摘要: The invention relates to compositions including at least one polyamide (A) and at least one copolymer (B) of ethylene and of at least one unsaturated carboxylic anhydride or acid, such that the impact/fluidity (IF) value of the compositions including 90 parts of (A) per 10 parts of (B) is higher than 1.5 in the case of the compositions containing essentially no glass fibres and such that the IF value of the compositions including 60 parts of (A) per 10 parts of (B) and of glass fibres is higher than 0.9; the IF value is defined as the ratio of the product (i) of the Izod notched impact at 23.degree. C. multiplied by the MFI (Melt Flow Index) of the composition including (A) and (B) to the product (ii) of the impact multiplied by the MFI of the same composition but not including (B).
