摘要: This invention relates to a process for stabilizing polymers with oligomeric carbodiimides containing at least one heterocyclic end group and stabilizers. The oligomeric carbodiimides may be compounds of the general formula (I): where A1, A2 are each independently, identically or differently, hydrocarbon groups having 2 to 20 carbon atoms, B1, B2 are each independently, identically or differently, heterocycles, C1-C30-alcohols, polyetherols, polyesterols, amines, polyether amines, polyester amines, thioalcohols, polyether thiols, polyester thiols; R1, R2 are each independently, identically or differently: n is an integer from 2 to 100, and A1, A2, B1 and B2 may each be substituted at any desired position by C1-C20-alkyl, C2-C20-alkenyl, C2-C20-alkynyl, C1-C20-alkoxy, carbonyl oxygen (═O) or halogen, with the proviso that at least one B1 or B2 substituent is a heterocyclic end group. The invention also relates to compositions of the oligomeric carbodiimides and mixtures.

摘要: 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.
