| 摘要 |
The present invention relates to a method for producing polyether carbonates containing alkoxysilyl groups in which (a) an unsaturated polyether carbonate polyol is reacted with (b) an alkoxysilane compound of formula (II) Si(X)m(R1)n(R2)o (II), where X = H, Y-S-H and Y = C1-C22 alkylene, C6-C14 arylene, C7- C14 aralkylene, C7-C14 alkylarylene; R1 = C1-C8-alkoxy, C7-C20-aralkoxy, C6-C14-aroxy, C7- C20-alkylaroxy; R2 = C1-C22 alkyl, C6-C14 aryl, C7-C14 aralkyl, C7-C14 alkylaryl, and m and n represent, independently of one another, an integer ≥ 1, o is zero or an integer ≥ 1 and m + n + o = 4. The invention further relates to the production of a polyurethane polymer using such a polyether carbonate, a cross-linked, siloxane group containing polymer and a molded part containing or consisting of said cross-linked polymer. |
