Silicon resins with thermo- or hydro-sensitive reversible or non-reversible crosslinking nodes capable of being obtained by the reaction: (a) a linear or cyclic polydiorganosiloxane (P) with at least one alkenyl function bound to silicon by an Si-C- bond, with at least one hydrocarbon compound (LH) bearing both a thiol function capable of chemically reacting with a polydiorganosiloxane (P) alkenyl function and at least one hydrogen bond generating grouping, or (b) a linear or cyclic polydiorganosiloxane (P) having at least one thiol, primary amine or secondary amine function bound to silicium by an Si-C- function, with at least one hydrocarbon compound (LH) bearing both an alkenyl function capable of reacting chemically with a thiol, polydiorganosiloxane (P), primary amine or secondary amine function and at least one hydrogen bond generating grouping. The resins of the invention can be used as adhesives or in the preparation of adhesives. |
