TL;DR: In this paper, the authors link the molecular structure of polycarboxylate-ether-type superplasticizers with the performance of cementitious systems in order to develop new products with enhanced properties, e.g. improved water reduction with a wide range of cements or reduced retardation of cement hydration.

TL;DR: In this article, a method for producing copolymers of poly-C2-C4 alkylene glycol)-mono-acrylic esters with acrylic ester or methacric ester and to the use of the polymers as liquefying additives in cement-containing preparations is described.

TL;DR: The use of comb polymers as additives in preparations containing a mineral binder was first proposed in this article, where the binding site to the carbon backbone of the comb polymer was defined.

TL;DR: In this article, the use of comb polymers which comprise a carbon backbone comprising polyether groups of formula A *-U-(C(O))k-X-(Alk-O)n-W A wherein * is the binding point on the carbon backbone of the comb polymer, U represents a chemical binding or an alkylene group having 1 - 8 C-atoms, X represents oxygen or a group NR, k is 0 or 1, n represents a whole number, wherein the average, in relation to the comb polymer, lies in the region of between

TL;DR: In this article, the authors defined polymers that are soluble in water or can be dispersed in water and contain alkoxylated diallylamine derivatives, such as dicarboxylic acids, anhydrides or mixtures thereof, and optionally at least one other ethylenically unsaturated monomer C.
