"Silylated polyurethanes and methods for preparing thereof" The present invention discloses silylated polyurethanes obtainable by reacting at least one polyols, at least one polyisocyanates, at least one silicon-containing heterocycle of the general formula (I): (I), wherein R1 is hydrogen; R2 and R3 are same or different and are, independently from one another, selected from a linear or branched, substituted or unsubstituted C1-C20 alkyl or C6-C18 aryl residue which may be interrupted by at least one heteroatom; R4 is selected from a linear or branched, substituted or unsubstituted C1-C20 alkylene residue which may be interrupted by at least one heteroatom; R5 and R6 are same or different and are, independently from one another, selected from the group consisting of hydrogen, a linear or branched, substituted or unsubstituted C1-C20 alkyl or C6- C18 aryl which may be interrupted by at least one heteroatom, and a C4-C8 cycloalkyl, or R5 and R6 may form a ring, preferably a 4- to 8-membered alkyl ring; and n is 0, 1 or 2, their preparation methods, curable compositions comprising the silylated polyurethanes, and their use as adhesive, sealant, spray foam and/or coating.
