  • Patent number: 12630676
    Abstract: A moisture curable silylated composition comprising: a polymer (A) comprising at least 2 alkoxysilyl terminal groups of formula (I): wherein R1 represents a hydrocarbon-based divalent radical comprising from 5 to 15 carbon atoms; R2 represents a C2-C4 alkylene; R3 represents a C1-C6 alkylene; R4 and R5 each represent a C1-C4 alkyl; R6 represents H or a radical comprising 1 to 6 carbon atoms; n is an integer such that Mw of the block of formula —[OR2]n— is 300 to 40000 g/mole; m is an integer different from 0 such that the Mw of the polymer (A) is between 500 to 50000 g/mole, and p is an integer equal to 0, 1 or 2; a polymer (B) comprising at least 2 alkoxysilyl terminal groups of formula (II): wherein R2, R4, R5, n and p are such as defined for formula (I); and an alkoxy modified silsesquioxane (C).
