Abstract
Semi-crystalline polyesters from isoidide and 2,5-furandicarboxylic acid are disclosed, as well as semi-crystalline copolyesters from isoidide and a minor amount of either 1,4-butanediol or 2,3-butanediol with 2,5-furandicarboxylic acid, together with processes for making high molecular weight materials by melt polymerization providing a semi-crystalline polymer then performing solid state condensation on the semi-crystalline polymer.
