  • Patent number: 9771437
    Abstract: The present invention describes the preparation of highly-performing “Acrylamide Free” polyelectrolytic polymers by using not toxic monomers and the way such new monomers can be advantageously used in the field of several civil and/or industrial applications. The new polyelectrolytic polymers developed herein can be then used both as replacement of the common acrylamide-based polymers and in the applications wherein the absence of residual toxic polymerization monomers is requested.

  • Patent number: 9745445
    Abstract: The invention disclose halogen free thermoplastic or cross linked polymers compositions comprising a polyolefin and/or a polyolefin containing polar co-monomers and a combination of metal hydroxides and inorganic hypophosphite as a synergic, and optionally other ingredients. These compositions show a superior balance of flame retardant properties compared to already known corresponding halogen free formulations. Molded items obtained using the polymer composition according to the present invention are useful in a wide range of injection molding and extrusion applications, especially cables.
