Реферат: The invention relates to copolymers which are based on mono or dicarboxylic acid derivatives, oxyalkylene glycol alkenyl ethers, vinyl polyalkylene glycol-, polysiloxane- or ester compounds in addition to the use thereof as additives for aqueous suspensions based on mineral or bituminous binding agents. The copolymers provide aqueous building material suspensions with excellent processing properties even in the smallest of doses without inhibiting resistance. The drastic reduction of the water/binding agent content achieved by the use of the inventive copolymers results in highly flowable building materials without any segregation of individual constituents in said building material mixture.
Copolymers based on phosphorous-containing monomers, process for the preparation thereof and their use
