Abstract
Polymer composition based on a mixture of 15 to 50% by weight of a propylene polymer and of 50 to 85% by weight of a flexible ethylene copolymer. The flexible ethylene copolymer is either a terpolymer (A) comprising from 83 to 92.7 mol % of ethylene, from 7 to 14 mole % of at least one alkyl (meth)acrylate, whose alkyl group has from 1 to 8 carbon atoms and from 0.3 to 3 mol % of at least one unsaturated dicarboxylic anhydride, or a mixture comprising, for 100 parts by weight, at least 70 parts by weight of the terpolymer (A) and at most 30 parts by weight of at least one copolymer (B) selected from ethylene copolymers comprising from 86 to 93 mol % of ethylene and from 7 to 14 mol % of at least one copolymerizable monomer selected from alkyl (meth)acrylates whose alkyl group has from 1 to 8 carbon atoms and ethylene copolymers comprising 92 to 98 mol % of ethylene and from 2 to 8 mol % of at least one C.sub.3 -C.sub.10 .alpha.-olefin, the said ethylen/.alpha.-olefin copolymers having a density in the range of 0.875 to 0.905, and the said terpolymer (A) having undergone at least a partial dynamic crosslinking, using a crosslinking agent containing at least one functional group capable of reacting with the anhydride functional group of the said terpolymer (A). Application to the production of moulded articles.
