Abstract

See full text

The invention relates to a process for the preparation of a polymerization mixture suitable as a dispersant and comprising a copolymer. In the process, a vinyloxyalkylpolyether derivative is reacted with an acid monomer derivative with formation of the copolymer in the presence of a free radical polymerization initiator by free radical polymerization, the free radical polymerization taking place in a medium which contains less than 25% by weight of water and in totality more than 60% by weight of copolymer, vinyloxyalkylpolyether derivative and acid monomer derivative.
