Polyurethane with polyether and polyester blocks and alkoxysilane end group |
摘要 |
<p>1) Method of preparing a polyurethane with polyurethane-polyether and polyurethane-polyester blocks with at least 2 polyurethane-polyester end blocks joined to an alkoxysilane end group, said method comprising: (i) reaction of a polyether polyol (A) with a stoichiometric excess of an aliphatic diisocyanate (B) then (ii) reaction of the polyurethane formed in step (i) with a stoichiometric excess of a polyester polyol (C), then (iii) reaction of the polyurethane formed in step (ii) with a stoichiometric amount of an isocyanatosilane (D). 2) Polyurethane formed by said method. 3) Corresponding adhesive composition, further comprising a crosslinking catalyst. 4) Method of assembly of 2 substrates employing said composition.</p> |
