COPOLIESTERI RAMIFICATI,SOLUBILI OPPURE DISPERDIBILI IN ACQUA E PROCEDIMENTO PER LA LORO PREPARAZIONE |
摘要 |
Water-soluble polyester having an apparent molecular weight between about 600 and about 5,000 and a SO3M group content between about 5 to about 40 mol percent based on the number of mols of dicarboxylic and/or polycarboxylic acids esterified in the polyester, and an at least trifunctional alcohol and/or an at least trifunctional carboxylic acid content between about 1 to about 40 mol percent based on the number of mols of dicarboxylic and/or polycarboxylic acids esterified in the polyester so that the polyester is correspondingly branched and M denotes a cation of an alkali metal, the ammonium ion or the cationic radical of an organic amine. The improved polyester is particularly suited as a levelling agent in the disperse dyeing of polyester fibers or the like. |
