Abstract:
A resin composition (c) which is based on polyethylene, comprising99.3%â€”higher than 50% of a polyethylene resin (a1) having a melt flow rate (MFR) according to ASTM D 1238 (190Â° C., 2160 g load) in the range from 0.001 to 0.5 g/10 min. and a density in the range from 0.945 to 0.980 g/cm3, 0.2-20% of a modified ethylene/&agr;-olefin copolymer (a2) which is modified by having grafted thereon an unsaturated dicarboxylic acid or its anhydride and has a density in the range from 0.900 to 0.940 g/cm3 and 0.5-30% of an ethylene/vinyl alcohol copolymer (b), based on the weight of the composition, and having a melt flow rate (MFR) according to ASTM D 1238 (190Â° C., 2160 g load) in the range from 0.001 to 0.2 g/10 min., a density in the range from 0.940 to 0.970 g/cm3 and an Izod impact strength (with notch), determined according to ASTM D 256 at minus 40Â° C., of at least 100 J/m.
