A first aspect of the subject of the invention is a (meth) homopolymer of acrylic acid at least one and / or (meth) after drying of the solution containing the copolymer at least one of acrylic acid and other monomers, at least one, at least one alkoxy polyoxyethylene or more alkylene glycol esterified and / or one or by amination alkoxy polyoxyalkylene obtained by alkylene amidated, or one functionalisation of drying the intermediate produced by the ethoxylated according to the alkylene oxide of two or more by (meth) relates to a process for preparing a comb-shaped polymer having an acrylic main chain and a polyoxyalkylene alkylation instrumental. The dried intermediate (loaded state to a dry state, or their aqueous solutions) The final comb-shaped polymer is also part of the subject of the invention. Finally, the preparation and use of the above-described polymer containing an inorganic or organic material represents a final aspect of the subject of the invention.
