Output (English): The polymer contains 75% and 95% by weight of an ethylene-alpha-olefin copolymer of formula CH 2 O = CHR, wherein R is an alkyl radical of 1 and 10 carbon atoms and 5 and 25% by weight of propylene copolymer. ethylene and at least one alpha-olefin of the formula CH 2. is an alkyl radical of 2 and 10 carbon atoms, and the copolymer is characterized by an insoluble bead in xylene of not more than 70% at 25 degC. The method of producing these mixtures is done in two reactors, in series, in a catalyst. \ T
