    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: Oligomeric carbodiimides comprising at least one heterocyclic end group are used as stabilizers for polymers. 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 wherein 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. Processes for stabilizing polymers against hydrolysis using oligomeric carbodiimides are also disclosed.
