Sulfonated copolyesters and manufacturing process |
| abstract |
A process for preparing a sulfonated copolyester and the process comprises: polymerizing a first prepolymer with a second prepolymer to form a sulfonated metal copolymer; reacting the metal sulfonated copolymer with a rapidly crystallizing polyester block to provide an amorphous sulfonated copolyester; and crystallizing the amorphous sulfonated copolyester to form a crystallized sulfonated copolyester; in which: the first prepolymer comprises the reaction product of a dicarboxylic acid or ester thereof, and a first alkylene diol; and the second prepolymer comprises the reaction product of an aromatic sulfonate, or a salt or ester thereof, with a second alkylene diol. |
