Polyester polymers and aqueous dispersions thereof
A water dispersible polyester polymer is described having one or more polyester chains and one or more non-ionic polyoxyalkylene chains in which at least 40 % of the repeating oxyalkylene units are oxyethylene units. The polyester polymer has a structure in which one or more of the polyoxyalkylene c...

Summary: | A water dispersible polyester polymer is described having one or more polyester chains and one or more non-ionic polyoxyalkylene chains in which at least 40 % of the repeating oxyalkylene units are oxyethylene units. The polyester polymer has a structure in which one or more of the polyoxyalkylene chains are pendent to at least one of the polyester chains. The polyoxyalkylene chains provide the polyester with non-ionic stabilisation enabling the polyester to form aqueous dispersions which possess good colloid stability. |
