Disclosed is a co-polymer based on oxyalkyleneglycol alkenyl ethers and unsaturated dicarboxylic acid derivatives, as well as vinylic polyalkyleneglycol, polysiloxane or ester compounds. These co-polymers can be used as additives for hydraulic binding agents, especially cement. The co-polymers of the invention have an excellent and long-lasting liquefying action without introducing large amounts of air pores into the binding agent mixtures, thereby preventing the loss of strength and stability of the hardened building materials.
