Abstract: A polyalkylene oxide ester polymer with a weight average molecular weight M w of 500 to 50 000 g/mol and a polydispersity PD of 2 to 6, comprising 10 to 560 ether groups and 2 to 51 ester groups, which are interconnected with alkylene groups, which is significantly better biodegradable than conventional polyalkylene oxide polymers, the preparation of such a polyalkylene oxide ester polymer and its use.
