2 5 FURAN DICARBOXYLIC ACID BASED POLYESTERS PREPARED FROM BIOMASS

摘要

310Polyesters described herein are prepared in whole or in part from biomass. In one aspect a copolyester is formed from monomers of 2 5 furan dicarboxylic acid or a lower alkyl ester thereof at least one aliphatic or cycloaliphatic C C diol and terephthalic acid. In another aspect a polyester is formed from monomers of 2 5 furan dicarboxylic acid or a lower alkyl ester thereof and isosorbide. In some aspects the polyester is polyethylene isosorbide furandicarboxylate poly(2 5 furandimethylene adipate) or polyvanillic ester. The polyesters may have desirable physical and thermal properties and can be used to partially or wholly replace polyesters derived from fossil resources such as poly(ethylene terephthalate).
