(EN) SULFONATED ALIPHATIC-AROMATIC COPOLYESTERS AND SHAPED ARTICLES PRODUCED THEREFROM
(FR) COPOLYESTERS ALIPHATIQUES-AROMATIQUES SULFONES ET ARTICLES FORMES PRODUITS A PARTIR DE CES COPOLYESTERS
Abrégé
(EN)
Sulfonated aliphatic-aromatic copolyesters are provided. The copolyesters are produced from a mixture of aromatic dicarboxylic acids, aliphatic dicarboxylic acids, ethylene glycol, other glycols, and components containing alkali metal or alkaline earth metal sulfo groups, such as a metal 5-sulfoisophthalic acid derivative. The copolyesters have lower sulfonation than known sulfonated polyesters, and provide advantageous thermal properties for some end uses. The sulfonated aliphatic-aromatic copolyesters are useful in forming coatings or films on various substrates, and in packaging. Some compositions comprising the sulfonated aliphatic-aromatic copolyesters are biodegradable, as are some of the sulfonated aromatic-aromatic copolyesters.
(FR)
L'invention concerne des copolyesters aliphatiques-aromatiques sulfonés. Ces copolyesters sont produits à partir d'un mélange d'acides dicarboxyliques aromatiques, d'acides dicarboxyliques aliphatiques, d'éthylène glycol, d'autres glycols et de constituants renfermant des groupes sulfo de métaux alcalins ou de métaux alcalino-terreux, tels qu'un dérivé d'acide 5-sulfoisophtalique métallique. Lesdits copolyesters présentent un niveau de sulfonation inférieur à celui des polyesters sulfonés connus, et permettent d'obtenir des propriétés thermiques améliorées en vue de certaines utilisations finales. Ces copolyesters aliphatiques-aromatiques sulfonés sont utiles pour former des revêtements ou des films sur divers substrats et pour produire des emballages. Certaines compositions comprenant ces copolyesters aliphatiques-aromatiques sulfonés sont biodégradables, à l'instar de certains des copolyesters aromatiques-aromatiques sulfonés.
