Abstract

Official abstract text for this publication.

The present invention relates to a polymer and the associated polymerization process, and to the use of the polymers according to the invention for example as foam suppressant, for the dispersion of solids or as surfactant for washing or cleaning purposes. The polymer is prepared by polymerization of a) at least one alkylene oxide or a cyclic carbonate of the formula (I) where n is 1 to 10, m is 0 to 3 and R 1 is C 1 -C 10 -alkyl, C 2 -C 10 -alkenyl, aryl or aralkyl, b) glycerol carbonate, where the polymerization is carried out in the presence of at least one base.
