BIFURAN-MODIFIED POLYESTERS

Copolyesters such as polyethylene terephthalate (PET) or polyethylene furanoate (PEF) modified with bifuran polyacids such as dimethyl-2,2′-bifuran-5,5′-dicarboxylate (BFE), 2,2′-bifuran-5,5′-dicarboxylic acid (BDA), or bis(2-hydroxyethyl)-2,2′-bifuran-5,5′-dicarboxylate (BHEB), and/or bifuran polyh...

Beschreibung
Zusammenfassung:	Copolyesters such as polyethylene terephthalate (PET) or polyethylene furanoate (PEF) modified with bifuran polyacids such as dimethyl-2,2′-bifuran-5,5′-dicarboxylate (BFE), 2,2′-bifuran-5,5′-dicarboxylic acid (BDA), or bis(2-hydroxyethyl)-2,2′-bifuran-5,5′-dicarboxylate (BHEB), and/or bifuran polyhydroxyls, may have improved properties such as glass transition temperature (Tg), tensile modulus, barrier properties, crystallinity, and/or impact strength. Polyethylene terephthalate-co-bifuranoate (PETBF) has an improved Tg. Also described are polyethylene furanoate-co-bifuranoates (PEFBF).
