Title
(EN) SILYLATED POLYURETHANES, THEIR PREPARATION AND USE
(FR) POLYURÉTHANES SILYLÉS, LEUR PRÉPARATION ET LEUR UTILISATION
Abstract
(EN)
A silylated polyurethane obtainable by a process comprising the following steps: (a) reacting at least one polyol with at least one triisocyanate to form a hydroxyl-terminated polyurethane prepolymer, and (b) reacting said polyurethane prepolymer with at least one isocyanatosilane of the formula (1): OCN-R-Si-(X)m(R1)3-m, wherein m is 0, 1 or 2, each R1 is independently from each other a hydroxyl group, an alkoxy group having 1 to 10 carbon atoms, an acyloxy group having 1 to 10 carbon atoms, or -OCH(R2)COOR3, wherein R2 is hydrogen or an alkyl group having 1 to 4 carbon atoms and R3 is a straight-chain or branched alkyl group having 1 to 8 carbon atoms, each X is independently from each other an optionally substituted hydrocarbon group having 1 to 10 carbon atoms, which can be interrupted by at least one heteroatom, and R is a difunctional organic group, to endcap the hydroxyl groups on said prepolymer with said isocyanatosilane. The silylated polyurethanes are suitable for use in a preparation as an adhesive, sealant, or coating agent.

L'invention concerne un polyuréthane silylé pouvant être obtenu par un procédé comprenant les étapes suivantes, consistant à : (a) faire réagir au moins un polyol avec au moins un triisocyanate pour former un prépolymère de polyuréthane à terminaison hydroxyle et (b) faire réagir ledit prépolymère de polyuréthane avec au moins un isocyanatosilane de formule (1) : OCN-R-Si-(X)m(R1)3-m, dans laquelle m vaut 0, 1 ou 2, chaque R1 représente, indépendamment l'un de l'autre, un groupe hydroxyle, un groupe alcoxy comprenant 1 à 10 atomes de carbone, un groupe acyloxy comprenant 1 à 10 atomes de carbone, ou -OCH(R2)COOR3, dans laquelle R2 représente un atome d'hydrogène ou un groupe alkyle comprenant 1 à 4 atomes de carbone et R3 représente un groupe alkyle à chaîne droite ou ramifiée comprenant 1 à 8 atomes de carbone, chaque X représente, indépendamment l'un de l'autre, un groupe hydrocarboné éventuellement substitué comprenant 1 à 10 atomes de carbone, qui peut être interrompu par au moins un hétéroatome et R représente un groupe organique difonctionnel, pour coiffer les groupes hydroxyle sur ledit prépolymère par ledit isocyanatosilane. Les polyuréthannes silylés sont appropriés pour une utilisation dans une préparation en tant qu'adhésif, matériau d'étanchéité ou agent de revêtement.
