Toughened, low permeability, solvent and salt resistant polyamide blends

摘要

Compositions useful as a material for fuel lines comprising an intimate blend of: (I) from 45 to 55% by weight of a polyamide and (II) from 55 to 45% by weight of a mixture of (a) From 70 to 90% by weight of high density polyethylene grafted with an alpha, beta-olefinically unsaturated dicarboxylic acid anhydride, (b) From 5 to 15% by weight of linear low density polyethylene grafted with an alpha, beta-olefinically unsaturated dicarboxylic acid anhydride, and (c) From 5 to 15% by weight of ethylene/propylene/diene rubber grafte dwith an alpha, beta-olefinically unsaturated dicarboxylic acid anhydride are described. m
