Method for preparing a cross-linkable composition |
| abstract |
The present invention relates to a method for preparing a cross-linkable composition comprising at least one silylated polymer P with alkoxysilane end groups and at least one catalytic system B, the method comprising the following steps: - a) preparing a silylated polymer P with alkoxysilane end groups comprising: - a-1) the polyaddition reaction between a composition of polyol(s) and a composition of polyisocyanate(s) in the presence of a catalyst A selected from the bismuth and/or zinc-based carboxylates in order to prepare a polymer with NCO end groups; - a-2) the reaction of the polymer with NCO end groups obtained in step a-1) with an organosilane compound having at least one reactive function with the -NCO function of the polymer with NCO end groups; - b) placing the silylated polymer P obtained in step a) in contact with a catalytic cross-linking system B which is a mixture of zinc-based carboxylate(s) and cyclic amidine, the method being carried out without any tin-based catalyst. |
