Abstract: The present invention relates to a method of processing a workpiece comprising contacting a tool and a workpiece to effect a change in the shape of the workpiece, and applying a metalworking fluid to a surface area where the tool and the workpiece are in contact, where the metalworking fluid contains a propoxylate of the formula R—O—(C3H6O)n—H, where R is a branched C6 to C20 alkyl and n is from 3 to 30. The invention further relates to the metalworking fluid, and to a use of the propoxylate as additive in metalworking fluids.

Abstract: The present invention relates to biodegradable copolyesters with molecular weight Mn from 10 000 to 100 000 measured by GPC, obtainable via reaction of i) from 51 to 84% by weight, based on the copolyester, of a branched polyester middle block produced from aliphatic or aliphatic and aromatic dicarboxylic acids and from aliphatic dihydroxy compounds with molecular weight Mn from 5000 to 25 000 measured by 1H NMR with from 15.9 to 48.9% by weight, based on the copolyester, of a lactide in the presence of a catalyst, and then the resultant polyester triblock with molecular weight Mn measured by 1H NMR from 5800 to 49 500 with ii) from 0.1 to 3% by weight, based on the copolyester, of a diisocyanate. The present invention further relates to a process for the production of, and to the use of, the abovementioned biodegradable copolyesters.
