摘要： 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 ##STR1## where R.sup.1 and R.sup.2 are identical or different and each is a univalent aliphatic, araliphatic or aromatic hydrocarbon radical having 1 to 12 carbon atoms, orR.sup.1 and R.sup.2 are together a bivalent aliphatic, araliphatic or aromatic radical,R.sup.3 is an (n+1)-valent organic radical,A is a group capable of ester formation, n is an integer from 1 to 3,R.sup.4 and R.sup.5 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,R.sup.6 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.
