A mixture comprising at least one polyfunctional chain extender having at least three reactive groups, and at least one mono- or difunctional hydrolysis stabilizer, where the chain extenders and the hydrolysis stabilizers react with the terminal groups of polymers in the molten or solid state of the polymers to form a chemical bond. Use of such mixtures as stabilizers for polymers. Methods for stabilizing polymers with respect to molecular weight loss, where an effective amount of such a mixture is added to the polymer. |
