Sulfonated aliphatic-aromatic polyetherester films, coatings, and laminates

摘要: Articles, including films, coatings and laminates, are produced from certain sulfonated aliphatic-aromatic polyetherester compositions, which have an optimized combination of fast biodegradation rates enhanced thermal properties when compared to the compositions art. The articles may be further processed form useful shaped articles, such as sheets, thermoformed containers, that can applied to, for example, films or other substrates. disclosed polyetheresters based on copolyesters a mixture containing aromatic dicarboxylic acids, aliphatic poly(alkylene ether) glycols, components alkali metal alkaline earth sulfo groups.
