  • Cationic polymerization process for the synthesis of nano-structured polymers containing graphene
    Patent number: 9493594
    Abstract: A cationic polymerization process for the synthesis of nano-structured polymers containing graphene which comprises reacting graphite oxide dispersed in a solvent by means of ultrasounds, with at least one vinyl monomer and at least one vinyl aromatic monomer, in the presence of at least one strong inorganic acid and suitable for activating a cationic polymerization, wherein: —said graphite oxide contains from 5% to 60% by weight of bound oxygen, —said vinyl monomer contains at least one carboxylic group wherein the ratio between oxygen bound to the oxide and carboxylic groups ranges from 1:10 to 10:1 in moles per mole, and—the ratio between said vinyl aromatic monomer and the sum of the quantity of graphite oxide and vinyl monomer containing carboxylic groups ranges from 50% to 99% by weight.
    Type: Grant
    Filed: May 20, 2014
    Date of Patent: November 15, 2016
    Assignee: Versalis S.P.A.
    Inventors: Gino Goffredi, Aldo Longo, Olga Valentino, Riccardo Felisari, Alessandro Casalini

  • Process for the alkylation of aromatic compounds
    Patent number: 5866738
    Abstract: Process for the alkylation of aromatic compounds which comprises contacting an olefin with an aromatic hydro-carbon in the presence of a zeolite and under conventional operating conditions, characterized in that the aromatic hydrocarbon, before the alkylation, is: a) treated to eliminate the oxygen dissolved therein; and/or b) percolated through a fixed bed consisting of particles of alumina modified with silver.
