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). L'invention concerne des copolyesters tels que le poly(téréphtalate d'éthylène) (PET) ou le poly(furannoate d'éthylène) (PEF) modifiés par des polyacides bifuranne tels que le 2,2'-bifuranne-5,5'-dicarboxylate de diméthyle (BFE), l'acide 2,2'-bifuranne-5,5'-dicarboxylique (BDA) ou le 2,2'-bifuranne-5,5'-dicarboxylate de bis(2-hydroxyéthyle) (BHEB) et/ou des polyhydroxyles bifuranne, qui peuvent présenter des propriétés améliorées telles que la température de transition vitreuse (Tg), le module d'élasticité en traction, les propriétés barrière, la cristallinité et/ou la résistance au choc. Le poly(téréphtalate d'éthylène)-co-bifurannoate (PETBF) possède une Tg améliorée. L'invention concerne également des poly(furannoate d'éthylène)-co-bifurannoates (PEFBF).
