  • Coextrusion binder, its use for a multilayer structure and the structure thus obtained
    Patent number: 6746738
    Abstract: The present invention relates to a coextrusion binder comprising: 5 to 30 parts of a polymer (A), itself comprising a blend of a polyethylene (A1) of relative density between 0.935 and 0.980 and of a polymer (A2) chosen from elastomers, very low-density polyethylenes and ethylene copolymers, the (A1)+(A2) blend being cografted with an unsaturated carboxylic acid; 95 to 70 parts of a polyethylene (B) of relative density between 0.930 and 0.950; the blend of (A) and (B) being such that: its relative density is between 0.930 and 0.950, the content of grafted unsaturated carboxylic acid is between 30 and 10,000 ppm, the MFI (melt flow index) measured according to ASTM D 1238 at 190° C./21.6 kg is between 5 and 100. This binder is particularly useful for petrol tanks of structure: HDPE/binder/EVOH or PA/binder/HDPE.
