Method for crosslinking polymer based on boron and nitrogen, method characterized in that said polymer (A) containing per molecule at least one motif chosen from the formulas: = N-SiR¹₃ and -NH- formulas in which R¹, identical or different, represents a hydrocarbon radical, is brought into contact with an effective amount of compound (B) chosen from products having per molecule at least one boron atom to which at least two atoms are directly linked halogen and the products having the general formula (3): (BX - NR) n , formula (3) in which the index n is an integer between 3 and 10, preferably n is equal to 3, R represents l hydrogen atom, a hydrocarbon radical, an organosilylated hydrogenoorganosilylated radical and X represents a halogen atom. |
