  • Imidized polymers containing luminescent groups and method for obtaining them
    Patent number: 9187584
    Abstract: The present invention relates to photoactive polymers and copolymers of acrylic monomers comprising cycloimide units functionalized with at least one luminescent chromophore group, preferably photoluminescent. The present invention also relates to spectrum converters comprising the above photoactive polymers and copolymers and solar devices comprising said converters.
    Type: Grant
    Filed: December 17, 2009
    Date of Patent: November 17, 2015
    Assignee: ENI S.p.A.

  • Process for the purification of lanthanide carboxylates
    Patent number: 8188304
    Abstract: A process is described for the purification of lanthanide carboxylates which comprises a step in which the hydrocarbon solution deriving from the synthesis of lanthanide carboxylate, containing said carboxylate and impurities of the corresponding carboxylic acid and/or water, is treated with an aqueous solution of a base in order to obtain a pH of the aqueous phase ranging from 9.0 to 12.2 and/or a step in which the hydrocarbon solution containing lanthanide carboxylate is treated with a solid selected from Na2SO4, MgSO4, Mg(ClO4)2, molecular sieves 3 ?, molecular sieves 4 ?, molecular sieves 5 ? and molecular sieves 13 X. Analytical methods are also described, which allow the purity of the lanthanide carboxylates to be non-destructively measured.
