The invention provides novel copolyesters, fibers and films, nonwovens from the fibers and disposable products of the copolyesters such as diapers. The products are degradable under the conditions typically existing in waste composting processes, have low ingredient costs and yet provide strength and toughness properties adequate for end uses such as in disposable diapers. The copolyesters are based upon polyethylene terephthalate copolymerized with a 5-sulfoisophthalic acid and, if desired, a polyethylene ether, such as diethylene glycol, and include units from hydroxyacids selected for their melting points being lower than their decomposition temperatures.
