  • Patent number: 9957391
    Abstract: The present invention relates to the field of processing thermoplastic polymers, particularly the present invention relates to a process for manufacturing compacted material suitable for the use in thermoplastic polymers without a compounding step, comprising the steps of a) providing at least one primary powder material; b) providing at least one molten surface treatment polymer; c) simultaneously or subsequently feeding the at least one primary powder material and the at least one molten surface treatment polymer into the high speed mixer unit of a cylindrical treatment chamber; d) mixing the at least one primary powder material and the at least one molten surface treatment polymer in the high speed mixer, e) transferring the mixed material obtained from step d) to a cooling unit, as well as the compacted material obtained by this process and its use in thermoplastic polymers.

  • Publication number: 20050106965
    Abstract: A multilayer structure comprising (A) a fabric and (B) a polymeric layer comprising a substantially random interpolymer comprising in polymerized form i) one or more ?-olefin monomers and ii) one or more vinyl or vinylidene aromatic monomers and/or one or more sterically hindered aliphatic or cycloaliphatic vinyl or vinylidene monomers, and optionally iii) other polymerizable ethylenically unsaturated monomer(s); layer (B) being free from a substantial amount of tackifier. The multilayer structure has desirable haptics and surprisingly good drape properties. It is useful in many applications, for example as water-impermeable clothes, tablecloths, tents, water-impermeable covers, curtains, artificial leather or upholstery.
