摘要： The invention relates to polyether ester carbonates of the general formula (I), wherein R1, R5 are independently linear or branched, saturated or unsaturated alkyl groups with 6 to 21 C atoms, R2, R4 are independently alkyl groups with 2 to 4 C atoms, R3 is a saturated or unsaturated, linear or branched, bivalent carbohydrate group with 1 to 22 C atoms, k is 0 or 1 to 50, l is 1 to 300, n is 2 to 50 and m is 2 to 50. The invention also relates to the use of the inventive carbonates as lubricants in spinning preparations for synthetic fibers. They are prepared by reacting alkoxylated fatty acids with diols and dialkyl carbonates.
