US 10,358,526 B2 · Moisture-curing polyether carbonate containing alkoxysilyl groups

Abstract

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.
