    • The invention relates to the use of oligomeric carbodiimides containing at least one heterocyclic end group as stabilizers for polymers. The oligomeric carbodiimides can be compounds of the general formula (I), in which A1, A2 are identical or different and represent hydrocarbon groups with 2 to 20 carbon atoms independently of each other; B1, B2 are identical or different and represent heterocycles, C1-C30 alcohols, poyletherols, polyesterols, amines, polyetheramines, polyesteramines, thioalcohols, polyetherthiols, polyesterthiols independently of each other; R1, R2 are identical or different and represent (A) independently of each other; and n represents a whole number ranging from 2 to 100; wherein A1, A2, B1 and B2 can each be substituted with C1-C20 alkyl, C2-C20 alkenyl, C2-C20 alkinyl, C1-C20 alkoxy, carbonyl oxygen (=O), or halogen at any position with the proviso that at least one substituent of B1 or B2 is a heterocyclic end group. The invention further relates to methods for stabilizing polymers against hydrolysis using oligomeric carbodiimides.
    • 使用含有至少一个杂环端基低聚碳二亚胺,作为稳定剂用于聚合物。 其中低聚碳化二亚胺可以是通式(I)化合物,其中A1,A2,彼此独立地,相同或不同,是具有2至20个碳原子,B1,B2彼此独立地,相同或不同,杂环,C1-C30醇的烃基, Poyletherole,聚酯多元醇,胺,聚醚,聚酯胺,硫醇,Polyetherthiole,Polyesterthiole,R1,R2彼此独立地,相同或不同,(A)中,n为整数2至100,并且其中A1,A2,B1和B2 在每种情况下通过C1-C20烷基,C2-C20链烯基,C2-C20炔基,C1-C20烷氧基,羰基氧(= O)或卤素的任何位置可被取代,其条件是至少一个取代基 是B1或B2的杂环端基。 此外,对于通过低聚碳二亚胺稳定对抗水解的聚合物的方法。
