    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).

    摘要： The present invention relates to a metal surface coated with a thermoplastic polymer, the coating exhibiting a peel strength at 130° C. (according to DIN 30 670) which is higher than 400 N/5 cm. This value can be obtained by placing between the metal and the thermoplastic a layer of epoxy resin of Tg higher than 120° C. against the metal and then a layer of polypropylene-based binder. The invention is particularly useful for coating the external surface of pipes.

    摘要： The present invention relates to mixtures of bitmen, of powdered rubber waste and of at least one copolymer (A) of an alpha-olefin and of at least one unsaturated epoxide, such that:the Brookfield viscosity at 180.degree. C. according to NFT Standard 76102 (27 needle) is lower than 1150 mPa s;the difference in absolute value of the softning points (ring-and-ball temperature) according to NFT 66008 between the top and bottom fractions of a mixture stored for 3 days at 180.degree. C. in a vertical tube is smaller than or equal to 5.degree. C. These mixtures are useful as road binders.
