摘要： The present invention relates to polyester that can be obtained by polymerization of a) terephtalacid dimethylester, and b) ethylene glycol, and c) 1,2-propylene glycol, and d) one or a plurality of polyethylene glycols having weight average molecular weights in the range of 1,000 to 2,000 g/mol, and e) one methyl polyethylene glycol having a weight average molecular weight in the range of 1,050 to 1,350 g/mol, f) either when a plurality of compounds having a reticulating effect and 3 to 6 functions that are enabled for polycondensation are present or absent. The polyester according to the invention can be used in an advantageous manner, e.g. to modify hydrophobic surfaces, which can be used, e.g., in paper recycling.

摘要： The present invention relates to the use in washing and cleaning agents of one or a plurality of polyesters which can be obtained by polymerisation of a) terephthalic acid dimethyl ester, and b) ethylene glycol, and c) 1,2-propylene glycol, and d) one or a plurality of polyethylene glycols with mass-average molecular weights in the range from 1000 to 2000 g/mol, and e) a methyl polyethylene glycol with a mass-average molecular weight in the range from 1050 to 1350 g/mol, f) either in the presence of or in the absence of one or a plurality of cross-linking compounds with 3 to 6 polycondensation-capable functions. The polyesters are particularly suited for use in the washing and cleaning agents as dispersants or as soil release polymers.
