Described are low-pill, low-flammability linear fiber-forming polyesters formed from dicarboxylic acid and diol components, which polyesters contain in their polymer chain modifying units formed by esterification or transesterification from compounds of the formulae I and/or II and/or III <IMAGE>nd R2 are identical or different and each is a univalent aliphatic, araliphatic or aromatic hydrocarbon radical having 1 to 12 carbon atoms, or R1 and R2 are together a bivalent aliphatic, araliphatic or aromatic radical, R3 is an (n+1)-valent organic radical, A is a group capable of ester formation, n is an integer from 1 to 3, R4 and R5 are identical or different and each is hydrogen or a univalent aliphatic, araliphatic or aromatic hydrocarbon radical having 1 to 12 carbon atoms, y is an integer from 1 to 10, R6 is hydrogen or a univalent aliphatic, araliphatic or aromatic hydrocarbon radical having 1 to 12 carbon atoms, and the index z is 0 or an integer from 1 to 2*i and the index i is a sufficiently small integer. Also described are processes for producing these polyesters and their use.
