Abstract

The present invention relates to copolymers, in particular dispersants for mineral binders, comprising or consisting of (i) monomeric units A of the general formula (I) <img class="EMIRef" id="2ef5e38b-9ef9-4af0-83c2-de7e7b984d1f-ia01" /> (ii) monomeric units B of the general formula (II) <img class="EMIRef" id="2ef5e38b-9ef9-4af0-83c2-de7e7b984d1f-ia02" /> and (iii) monomeric units C of the general formula (III) <img class="EMIRef" id="2ef5e38b-9ef9-4af0-83c2-de7e7b984d1f-ia03" /> The present invention also relates to the use of such copolymers as plasticizers for mineral binder compositions. Especially, copolymers of the present invention have been found to yield a high initial slump flow of mineral binder compositions and to retain a high slump flow thereof over longer periods of time.
