  • Patent number: 8754138
    Abstract: The present invention concerns polymers obtained by anionic initiation and bearing functions that can be activated by cationic initiations that are not reactive in the presence of anionic polymerization initiators. The presence of such cationic initiation functions allow an efficient cross-linking of the polymer after molding, particularly in the form of a thin film. It is thus possible to obtain polymers with well-defined properties in terms of molecular weight and cross-linking density. The polymers of the present invention are capable of dissolving ionic compounds inducing a conductivity for the preparation of solid electrolytes.

  • Patent number: 8298582
    Abstract: A polysaccharide-based solid material including, in its mass, at least one active agent having bactericidal, fungal, insecticidal and/or flame-retardant properties, and at least one complexing agent and/or at least one polymeric matrix having a complexing agent. The active agent includes at least one compound selected from the group including boron, silica, aluminum, phosphorus, iodine, derivatives thereof, aluminosilicate derivatives, and mixtures thereof. The solid material is characterized by an improved stability and by reduced environmental impact, and makes it possible to prepare materials based on wood particles and woods having a particular resistance against environmental attacks such as moisture.

  • Publication number: 20050159561
    Abstract: The invention concerns a copolymer of ethylene oxide and at least one substituted oxirane carrying a cross-linkable function. The copolymer comprises ethylene oxide, —O—CH2—CHR— units in which R is a substituent containing a reactive function which is cross-linkable by free radical process, and possibly —O—CH2—CHR?— units in which R? is a substituent containing no reactive function which is cross-linkable by means of a free radical process, It is characterized by an excellent polydispersity index I=MW/Mn and a random distribution of the different monomer units. The copolymer is prepared by an anionic copolymerization process. The copolymer is useful for preparing a solid electrolyte having good mechanical properties, a good cationic conductivity and a good chemical compatibility with the electrodes of a generator operating with alkali metals such as lithium and sodium.
