Claim 1:
2. The self-adhesive article according to claim 1, wherein the at least one polysilylated polymer(s) A) correspond(s) to the following formula:
formula (I):, wherein:
B represents a divalent hydrocarbonated radical (for f=2) or trivalent (for f=3) comprising 2 to 66 carbon atoms, linear, branched, cyclic, alicyclic or aromatic, saturated or unsaturated, optionally comprising one or more heteroatoms,
R3 represents a linear or branched divalent alkylene radical comprising from 1 to 6 carbon atoms,
R′2 represents a linear or branched divalent alkylene radical comprising from 2 to 4 carbon atoms,
R4 and R5 identical or different, each represent a linear or branched alkyl radical comprising from 1 to 4 carbon atoms, R4 which can optionally be engaged in a ring,
n″ is a non-zero integer whereby the number-average molecular mass of the polyether block of formula —[OR′2]n″-ranges from 150 g/mol to 20,000 g/mol,
p is an integer equal to 0 or 1,
f is an integer equal to 2 or 3, and
the numbers n″ and f are such that the number-average molecular mass of the at least one polysilylated polymer(s) A) is as defined in claim 1.
