Abstract: An adhesive tape includes a substrate [I] and an adhesive agent layer of a polyester adhesive agent provided on at least one of opposite surfaces of the substrate [I]. The substrate [I] is one selected from a polyolefin resin foam substrate, a urethane resin foam substrate, and an acrylic resin foam substrate. The polyester adhesive agent is made from a polyester adhesive agent composition [II] which contains a polyester resin (A) having a weight average molecular weight of 5,000 to 300,000, and having a structural unit derived from a polyol and a structural unit derived from a polyvalent carboxylic acid compound containing an aromatic structure-containing compound in a proportion of not greater than 80 mol %. The adhesive tape is excellent in adherence between a polyester adhesive agent layer and a polyolefin resin foam substrate, a urethane resin foam substrate, or an acrylic resin foam substrate.

Abstract: A polyester including ethylene 2,5-furandicarboxylate units is prepared in a process, where in an esterification step a 2,5-furandicarboxylate compound is reacted with ethylene glycol to form an ester composition, including components with 2-hydroxyethyl and 2,5-furandicarboxylate moieties; where in a polycondensation step the ester composition thus obtained is subjected to polycondensation at reduced pressure in the presence of a polycondensation catalyst to obtain a polycondensate; and where during the polycondensation step 2,5-furandicarboxylic acid is added to the ester composition.
