Abstract

The plasticity of ceramic compositions and dispersions can be improved by addition of at least one polymer (I) with recurring succinyl units. This effect can be reversed by addition of a setting accelerator (II); preferred setting accelerators are polymers (II) of the polyalkylenepolyamine type.
