Abstract
The invention relates to the use of at least one comb polymer which includes side chains which have at least one cationic group, and does not include side chains having polyether groups, and which has a main chain which has carboxyl groups, as dispersant for hydraulically settable compositions. The invention also relates to hydraulically settable cement compositions, mouldings, comb polymers and method for producing comb polymers.
Claims15
A use of at least one comb polymer which comprises side chains which have at least one cationic group, and which does not comprise side chains which have polyether groups, and which has a main chain which has carboxyl groups, as a dispersant for hydraulically settable compositions.
A hydraulically settable composition containing a hydraulically settable binder and at least one zwitterionic comb polymer, comprising a main chain which has carboxyl groups, and side chains which have a cationic group, wherein the comb polymer does not comprise side chains having polyether groups.
A zwitterionic comb polymer comprising a main chain which has carboxyl groups and side chains which have at least one cationic group, wherein the comb polymer does not comprise side chains having polyether groups.
