Beschreibung
Zusammenfassung:	An amorphous polyester or copolyester composition comprises the reaction product of a crystalline or semicrystalline polyester or copolyester, optionally derived from a recycled waste stream, at least one diol or aromatic diacid or an ester of a diacid or a hydroxycarboxylic acid or a lactone or a dianhydride, and a catalyst, wherein the amorphous composition has a weight average molecular weight of at least 10,000 g/mol (polystyrene equivalent molecular weight) as measured by gel permeation chromatography.
