A multi-layer hose having a multi-layer structure comprising an inner layer (I) made of a fluorocopolymer and an outer layer (II) made of a polyamide resin, wherein the fluorocopolymer constituting the inner layer (I) is a fluorocopolymer which comprises polymerized units (a) based on tetrafluoroethylene, polymerized units (b) based on ethylene and polymerized units (c) based on itaconic anhydride and/or citraconic anhydride, wherein the molar ratio of (a)/(b) is from 20/80 to 80/20 and the molar ratio of (c)/((a)+(b)) is from 1/10,000 to 5/100 and which has a volume flow rate of from 1 to 1,000 mm/sec., and the polyamide resin constituting the outer layer (II) is polyamide 11 and/or polyamide 12, which satisfies a condition of (terminal amino group concentration)/(terminal carboxyl group concentration)&#x3e;1.

Multi-layer hose

A hose for fuel having a laminated structure comprising an inner layer (A) made of a ethylene/tetrafluoroethylene copolymer adhesive to a polyamide resin and an outer layer (B) made of a polyamide resin, is formed. Such a hose for fuel is excellent in interlaminar adhesive strength and also excellent in antistatic properties and fuel permeation-preventing properties, and particularly, the dependency of the interlaminar adhesive strength on the take-up speed during the co-extrusion molding, is small.

A polyamide resin composition comprising: (A) 100 parts by weight of at least one member selected from a polyamide-11 resin and a polyamide-12 resin; optionally (B) from 3 to 30 parts by weight of a modified polyolefin resin; and (C) from 3 to 25 parts by weight of a plasticizer mixture comprising a plasticizer (C1) and a plasticizer (C2). The modified polyolefin resin (B) is either a modified polyolefin (B1) which is a copolymer of an olefin comprising at least one of ethylene and propylene, with an .alpha.,.beta.-unsaturated carboxylic acid or a derivative thereof, or a modified polyolefin (B2) which is a graft polymer obtained by grafting an .alpha.,.beta.-unsaturated carboxylic acid or a derivative thereof onto a copolymer of an olefin comprising at least one of ethylene and propylene. The plasticizer (C1) has a solidifying point of -40.degree. C. or lower and is at least one member selected from the group consisting of phthalic esters, fatty acid esters, polyhydric alcohol esters, phosphoric esters, trimellitic esters, and epoxy plasticizers, and the plasticizer (C2) is at least one member selected from the group consisting of benzenesulfonic acid alkylamides, toluenesulfonic acid alkylamides, and alkyl hydroxybenzoates.
