Process for the preparation of compositions containing a termoplasticas copolimero based on ethylene and maleic anhydride, and articles obtained from these compositions Industrial

摘要

Thermoplastic composition comprising a mixture of 25-80% by weight of at least one partially crystalline polymer or copolymer of ethylene which has a density of 0.870-0.945, of 15-85% by weight of at least one random copolymer containing 83-99.7 mol% of units derived from ethylene, 0-14 mol% of units derived from at least one ester of acrylic or methacrylic acid and 0.3-3 mol% of units derived from maleic anhydride, and having a melt index of 1-500 dg/min, of 1-8% by weight of at least one rubber, and of 0-8% by weight of talc; the use of this composition for the manufacture of a film which has adhesive properties; an industrial article comprising a metal coated with at least one layer of this composition; and a composite film comprising at least one layer comprising this composition, with the condition that the proportion of talc in the latter does not exceed the proportion which is sufficient to provide an antiblocking effect, and at least one layer of another thermoplastic substance.
