Structure and characterization of random aliphatic–aromatic copolyester.

Highlights: [•] New aliphatic–aromatic copolyester was synthesized from petrochemical raw materials. [•] 1H NMR analysis indicated random distribution of aliphatic and aromatic comonomers. [•] Solidification of copolyester is by crystallization of aromatic component only. [•] Small angle X-ray scattering does not indicate the existence of “long period”. [•] Fibrous crystals are arranged in spherulites filling completely the material volume. [ABSTRACT FROM AUTHOR]
