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.

The present invention relates to acrylic block polymers, either block copolymers or homopolymers, synthesized by a controlled free-radical process, and their use as low temperature flow modifiers in bio-derived fuel compositions. They are especially useful in modifying the low temperature flow behavior in bio-derived fuels. The acrylic polymers are especially useful as cold filter plugging control additives in bio-derived fuels.

A composite sheet is manufactured by depositing a multi-layer coating on the outer surface of a substrate, the coating comprising a metal layer and an outer polymeric layer formed from a precursor comprising a composition capable of being polymerized and / or cross-linked by free-radical processes. After the precursor is applied, the composite sheet is exposed to beam radiation and ozone, which both promote conversion of the precursor. The function of the cured polymeric layer includes protecting the metal layer from corrosion. The use of both beam radiation and ozone promotes substantially full conversion and curing of the precursor, even in portions of the substrate that are geometrically shadowed from incident beam radiation.
