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.
