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).

The invention relates to improved bitumen compositions including: (A) 100 parts of bitumen (B) 0.1 to 10 parts of a copolymer of an alpha-olefin, of an unsaturated epoxide and of an ester of unsaturated carboxylic acid (C) 0.1 to 10 parts of a copolymer of an alpha-olefin and of an ester of unsaturated carboxylic acid, (D) 0 to 10 parts of a thermoplastic elastomer (E) 0 to 10 parts of a polymer which is reactive with (B) (F) 0 to 10 parts of an ethylene/vinyl acetate copolymer. These bitumens are stable when stored and resist rutting.
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.
