PCT No. PCT/FR90/00145 Sec. 371 Date Dec. 27, 1990 Sec. 102(e) Date Dec. 27, 1990 PCT Filed Mar. 2, 1990 PCT Pub. No. WO90/10665 PCT Pub. Date Sep. 20, 1990.Modified polymers based on a graft polyester comprising: a backbone derived from a water-dispersible sulphonated polyester 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: preemulsion, in water, of a solution of an organopolysiloxane in one or more vinyl monomers 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. |
