The invention relates to a polymer composition, comprising: a polyether-polyester copolymer, a transition metal catalyst, and an active material that acts on, interacts or reacts with moisture wherein the polyether-polyester copolymer comprises (i) polyether segments wherein at least one polyether segment contains at least one polytetramethylene oxide segment, (ii) polyester segments, (iii) bridging elements of the structure –CO-R2-CO-, wherein R2 represents an optionally substituted bivalent hydrocarbon residue consisting of 1 to 100 carbon atoms; (iv) one or two end-caps R1-O-(C2-C4-O-)e-*, wherein R1 is an optionally substituted hydrocarbon residue and e is an integer of from 0 to 1000. The invention also concerns use of the polymer composition as well as an article of manufacture comprising the polymer composition.
