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 12):
The preparation process as claimed in  claim 1 , characterized in that the aminosilane C corresponds to the formula:\n R 2 NH\u2014R 3 \u2014Si(R 4 ) p (OR 5 ) 3-p \u2003\u2003(II) in which:\n R 2  represents a hydrogen atom or a linear, branched or cyclic C 1 -C 7  radical, which may be an alkyl, aliphatic or aromatic radical; \n R 3  represents a linear or branched divalent alkylene radical comprising from 1 to 4 carbon atoms, optionally substituted with a C 1 -C 4  alkyl radical: \n R 4  and R 5 , which may be identical or different, each represent a linear or branched alkyl radical of 1 to 4 carbon atoms, with the possibility when there are several radicals R 4  (or R 5 ) that they may be identical or different; and \n p is an integer equal to 0, 1 or 2.
