Abstract
Modified polymers based on a graft polyester comprising: PA0 a backbone derived from a water-dispersible sulphonated polyester PA0 and grafts consisting of copolymer units derived from at least one vinyl monomer and at least one ethylenically unsaturated organopolysiloxane soluble in the said vinyl monomer or monomers. They are prepared by: PA0 preemulsion, in water, of a solution of an organopolysiloxane in one or more vinyl monomers PA0 followed by addition of the emulsion obtained to an aqueous solution of a water-dispersible sulphonated polyester and polymerization in the presence of a water-soluble or water-dispersible initiator. They can be used as coating agents.
