  • NANOSTRUCTURED THERMOPLASTIC POLYAMIDE-GRAFTED POLYOLEFIN COMPOSITION
    Publication number: 20200071528
    Abstract: A composition including at least two grafted copolymers having a polyolefin basic polymer chain and polyamide grafts, the polyamide grafts being 5 wt % and 35 wt % of the composition bonded to the first and second copolymer as well as a third component selected among certain polyamides, polyethylenes or polypropylenes or a mixture thereof. Also, a multilayer structure including a plurality of adjacent layers, at least one of which is the aforementioned composition.

  • Thermoplastic composition made of polypropylene and polyamide-grafted polyolefin
    Patent number: 10280295
    Abstract: A composition of a blend of polypropylene, which may be present at between 10% and 90% by weight of the blend, and a polymer having a polyolefin core and polyamide grafts, optionally with an EPDM and/or a functional additive, which may be present at between 10% and 90% by weight of the blend. Also, a multilayer structure including a plurality of adjacent layers, at least one of which is the aforementioned composition.

  • Thermoplastic composition, in particular for photovoltaic modules
    Patent number: 9978897
    Abstract: A thermoplastic composition including a mixture of three particular and different polyolefins, including one of a polyamide-grafted polyolefin having particular polyamide grafts (type and quantity), for example, a polyamide-grafted polymer having a polyolefin trunk containing a residue of at least one unsaturated monomer and a plurality of polyamide grafts. Also, a thermoplastic film and, more specifically, a film for encapsulating a photovoltaic module incorporating the polyamide-grafted polyolefin composition.
