Summary: | 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; andf) at least one tertiary hydroxyl functional alkoxysilane of the general formula (I)wherein Ris selected from the group consisting of hydrogen and a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; Rand Rare 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; Ris selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; Ris selected from a linear or branched, substituted or unsubstituted hydrocarbon residue having 1 to 20 carbon atoms; Rand Rare 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. |
