Definitions

the present invention relates to a new composition of metallocene plastomer and of ethylene / alkyl (meth) acrylate copolymer, as well as to the objects obtained from this.
Copolymers of ethylene and alpha-olefin obtained by metallocene monosite catalysis are known. These copolymers being homogeneous in composition, it has been possible to prepare products having a density of, for example, between 0.905 and 0.880 g / cm 3 , called plastomers, having good mechanical and optical properties.
US-P-3176052 describes a homogeneous mixture comprising, by weight, (a) 25 to 95% of an ethylene / alpha-olefin copolymer obtained by Ziegler-Natta catalysis having a density greater than 0.92 g / cm 3 and a MFI of between 0.1 and 10 dg / min, heterogeneous in composition, and (b) 75 to 5% of a radical polyethylene having a density of between 0.91 and 0.94 g / cm 3 .
US-P-4623581 describes a homogeneous mixture comprising, by weight, (a) 25 to 98% of a heterogeneous ethylene / alpha-olefin copolymer in composition having a density between 0, 905 and 0.940 g / cm 3 and an MFI included between 0.4 and 3 dg / min, and (b) 75 to 2% of a radical polyethylene having a density between 0.91 and 0.94 g / cm 3 , having a polydispersity index greater than 4, said copolymer having specific properties of crystallinity and distribution of alpha-olefin monomers.
the radical polyethylene according to this document can be a copolymer of ethylene with up to 25% by weight of an alkyl acrylate, for example 17.5% by weight of butyl acrylate.
alkyl acrylate for example 17.5% by weight of butyl acrylate.
these modified ethylene polymers do not have a polydispersity index of between 2.7 and 4.1 (with reference to document EP-A-0006110); these modified ethylene polymers therefore have a satisfactory rheology which does not need to be modified.
EP-A-0006110 describes a mixture comprising, by weight,
EP-A-0597502 describes compositions comprising an ethylene metallocene polymer having a density of at least 0.900 g / cm 3 , also intended for the manufacture of heat-shrinkable films. According to this document, this polymer metallocene can be mixed with a thermoplastic polymer of the radical ethylene copolymer type. Although the ethylene / acrylate copolymers are specifically mentioned, the only examples aim to add EVA.
the flexural modulus of each copolymer is between 10 and 100 MPa.
the ratio of the flexural modules, as well as the secant modules, is advantageously greater than 1.
the ethylene / alkyl (meth) acrylate radical copolymer has, for example, an MFI of between 0.3 and 10.
metallocene ethylene / alpha-olefin copolymer designates these copolymers obtained by metallocene catalysis, and will be indifferently called “plastomers” or "ethylene metallocene copolymer” in the present description.
