  • POLYMER HAVING ADHERENCE PROPERTIES
    Publication number: 20170218116
    Abstract: The present invention relates to the field of polymers used to form coatings at the surface of supports. More particularly, the invention relates to a polymer having adhesion properties, in particular with regard to an organic or inorganic support, characterized in that it comprises at least one and preferably several consecutive or non-consecutive structural units of formula (I): in which: B represents a carbonyl or —NR?— unit with R? representing a hydrogen atom, a C1 to C6 alkyl radical, or a C5 to C6 aryl, carbamate or acyl radical; and R represents: a hydrogen atom, a linear or branched, saturated or unsaturated C1 to C6 hydrocarbon-based radical which, where appropriate, is substituted with one or more halogen atoms, a C5 to C6 aryl radical, or an acyl, acyloxy, alkoxycarbonyl or cyano radical.

  • Method for partial or total oxidation of one or several thiocarbonylthio ends of a polymer obtained by radical polymerisation controlled by reversible addition-fragmentation
    Patent number: 7473740
    Abstract: The present invention relates to a method for partial or total oxidation of one or several thiocarbonylthio ends of a polymer, obtained by radical polymerisation controlled by reversible addition-cleavage with thiocarbonylthio agents, Said method comprising the step of contacting said polymer with an ozone-containing gas, during which ozone reacts with the one or several thiocarbonylthio ends.

  • Method of preparing benzazepines and derivatives thereof
    Publication number: 20070185323
    Abstract: The invention relates to a method of preparing benzazepine compounds having general formula (IA) consisting in reacting at least one compound having general formula (IIA) with an olefin, the compound thus obtained then being cyclised such as to produce tetralone, followed by the oxime derivative of same, which, by transformation by a Beckmann rearrangement, gives rise to the desired compounds.
