Abstract: The invention provides novel polyesters, fibers and films, nonwovens from the fibers and disposable products of the polyesters 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 terephthaltate copolymerized with a monomer containing an alkali metal or alkaline earth metal sulfo group, a polyethylene ether, such as diethylene glycol, and include units from aliphatic hydroxyacids selected for their melting points being lower than their decomposition temperatures.

Abstract: The invention provides novel blends and concentrates of plasticized copolyesters, shaped articles of such blends, including films, fibers, foams, nonwovens from the fibers and disposable products such as diapers, and other compositions and uses, such as for coatings and adhesives. The products are degradable under conditions typically existing in waste composting processes, have low ingredient costs and provide improved strength and especially toughness properties on account of plasticizing e.g., with poly(alkylene) ether glycols, especially PEG of adequate molecular weight. The polyesters are based upon polyethylene terephthalate copolymerized with other ingredients, including non-aromatic diacids, such as adipic and glutaric acids, polyethylene ether groups, such as diethylene glycol or higher polyalkylene glycols, and hydroxy acids.
