PROCESS FOR PREPARING BRANCHED POLYETHERCARBONATES AND USE THEREOF

摘要

The present invention relates to a process for preparing branched polyethers and/or polyether-like structures, to these branched polyethers themselves, and to their use.

主权项

1. A process for preparing branched polyethers or polyether-like structures, comprising:
(a) reacting a starter of the general formula (II) with one or more reactants suitable for ring-opening polymerization to obtain a first reaction mixture, wherein formula (II) is:
Z(X—H)j  (II);where:
X independently at each occurrence O, NH, N-alkyl, N-aryl or S;j=1-10; andZ=any organic radical, with each X being linked to a carbon atom of the organic radical; (b) reacting the first reaction mixture obtained in step (a) with glycerol carbonate to obtain a second reaction mixture; and (c) reacting the second reaction mixture obtained in step (b) with one or more reactants suitable for ring-opening polymerization.
