摘要: The present invention provides certain sulfonated copolyetherester compositions containing hydroxyalkanoic acids and processes for producing such aromatic copolyetheresters. further shaped articles, preferably in the shape of films, coatings laminates, having improved thermal properties, wherein articles are produced from compositions. Some these materials also biocompostable. copolyetheresters a mixture an dicarboxylic acid component, sulfonate poly(alkylene ether) glycol optional other branching agent, color reducing agent.
