Abstract
Unsaturated compounds of formula (I): wherein: R, R, and Rare each independently H or CH; Ris a linear or branched C-C-alkylene; Rand Rare each independently H, C-C-alkyl, C-C-cycloalkyl, aryl, —CH—O—C-C-alkyl, or —CH—O—C-C-alkenyl, where Rand Rmay together form a C-C-alkylene; Ris independently H,C-C-alkyl, or where Ris C-C-alkyl or C-C-alkenyl; and n is an integer from 2 to 200. Mixtures and polymers including the unsaturated compounds of formula (I). A method for preparing polymers by free-radical polymerization of monomers including the unsaturated compounds of formula (I). A process for preparing polymers including polymer-analogous reactions. And polymers including compounds (I) as cement additives, grinding aids, hydraulic binder additives, concrete plasticizers, reactive plasticizers for preparing plastics, rubber, or latex, associative thickeners and antioxidants, or for preparing polyether siloxanes.
