Abstract:
1) Process for preparing a poly(urea-urethane) comprising blocks of polyurethane-polyether and polyurethane-polyester type, two blocks of the same type each being connected to an alkoxysilane end group via a urea function, said process comprising: (i) the reaction of a polyether polyol A 1  with a stoichiometric excess of a diisocyanate B (i) ; and then (ii) the reaction of the polyurethane produced in step (i) with a stoichiometric excess of a polyester polyol A 2 ; and then (iii) the reaction of the polyurethane produced in step (ii) with a stoichiometric excess of a diisocyanate B (iii) ; and then (iv) the reaction of the polyurethane produced in step (iii) with a stoichiometric amount of an aminosilane C.   2) Poly(urea-urethane) formed via said process. 3) Corresponding adhesive composition, also comprising a crosslinking catalyst. 4) Process for assembling two substrates using said composition.

Claim (Index 8):
The preparation process as claimed in  claim 1 , characterized in that the amounts of the reagents used in step (ii) correspond to an \u2014NCO/\u2014OH equivalent ratio of between 0.3 and 0.7, preferably equal to about 0.5.
