Moisture-curing polyether carbonate containing alkoxysilyl groups
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).sub.m(R1).sub.n(R2).sub.o (II), where XH, YSH 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.
POLYMER COMPOSITIONS AND METHODS
The present invention encompasses polymer compositions comprising aliphatic polycarbonate chains containing functional groups that increase the polymer's ability to wet or adhere to inorganic materials. In certain embodiments, chain ends of the aliphatic polycarbonates are modified to introduce silicon-containing functional groups, boron-containing functional groups, phosphorous-containing functional groups, sulfonic acid groups or carboxylic acid groups.
