Kilogram-scale preparation of sustainable PETG modified with a biobased cyclic diol derived from 5-hydroxymethylfurfural: From synthesis to properties

[Display omitted] •Kilogram-scale novel PETT copolyesters were successfully synthesized in 5L reactor.•The cyclic structure and ether group of THFDM reach a balance to the influence on Tg.•Kwei’s equation evaluated the Tg of copolyesters better than other theories.•The introduction of THFDM provides...
