Said polyurethanes contain patterns of the type (Ia) or (Ib) with A = alkyl, cycloalkyl, aryl, arylalkyl or alkylaryl, or polyoxyalkylene or polyester; D = alkylene, cycloalkylene, arylene, alkylarylene or arylalkylene, and can contain at least one heteroatom; E = (i), in which case G represents the hydrocarbonated skeleton of an organic compound containing at least two alcohol functions, or (ii), in which case G represents the hydrocarbonated skeleton of an organic compound containing at least two isocyanate functions, and Pv = a polymer sequence from at least one vinyl monomer. The presence of vinyl sequences in said polyurethanes makes it possible, in particular, to improve the stability when exposed to sunlight (UV) of paints with a polyurethane base, thereby adding a sheen to said paints.
2067489 9105767 PCTABS00105 Ces polyuréthanes comportent des motifs de type (Ia) ou (Ib), A = alkyle, cycloalkyle, aryle, arylalkyle ou alkylaryle, ou polyoxyalkylène ou polyester, D = alkylène, cycloalkylène, arylène, alkylarylène ou arylalkylène, et peut comporter au moins un hétéroatome, E = (i), auquel cas G représente le squelette hydrocarboné d'un composé organique comportant au moins deux fonctions alcool, ou bien (ii), auquel cas G représente le squelette hydrocarboné d'un composé organique comportant au moins deux fonctions isocyanate, et Pv = séquence polymère issue d'au moins un monomère vinylique. La présence de séquences vinyliques dans ces polyuréthanes permet notamment d'améliorer la stabilité au soleil (UV) des peintures à base de polyuréthanes et de donner un brillant à ces peintures.
