POLYMERIZATION MIXTURE THAT CAN BE PRODUCED WITHOUT WATER

摘要

The invention relates to a method for producing a polymerization mixture which comprises a copolymer and is suitable as a dispersant. In the method, a vinyloxyalkyl polyether derivative is reacted with an acid monomer derivative by way of radical polymerization in the presence of a radical polymerization initiator, to form the copolymer. The radical polymerization takes place in a medium which contains less than 25% by weight of water and, in total, more than 60% by weight of copolymer, vinyloxyalkyl polyether derivative and acid monomer derivative.
