A polyether ester comprises poly(trimethylene-ethylene ether) ester soft segment and alkylene ester hard segment. Preferably, the polyether ester is a thermoplastic elastomer in which the hard segment comprises C2 to C12 alkylene ester. The composition is prepared by providing and reacting: (a) poly(trimethylene-ethylene ether) glycol (b) at least one polyester. Fiber made from this composition is particularly useful in making films, membranes and fabrics.
