    摘要： The invention relates to a silylated polyurethane obtainable by reacting: d) at least one polyol having a number average molecular weight of from 1000 to 50,000 g/mol; e) at least one polyisocyanate, preferably diisocyanate; and f) at least one tertiary hydroxyl functional alkoxysilane of the general formula (I) wherein R1 is selected from the group consisting of hydrogen and a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; R2 and R3 are same or different and are, independent from one another, selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; R4 is selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; R5 is selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; R6 and R7 are same or different and are, independent from one another, selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; and n is 1, 2 or 3, a method for preparing thereof, a curable composition comprising the thereby obtained silylated polyurethane, and its use.
