A copolyester is provided comprising: a. at least one terephthalate acid residue; b. about 85 to about 96 mole % of ethylene glycol residues; c. about 4 to about 15 mole % of a combination of 1,4-cyclohexanedimethanol residues (CHDM) and diethylene glycol (DEG) residues; and d. a germanium catalyst present in the copolyester at a concentration of about 5 to about 500 ppm based on elemental germanium; wherein the terephthalate monomer is based on the substantially equal diacid equivalents of 100 mole % to diol equivalence of 100 mole % for a total of 200 mole %.
The present application discloses mixed cellulose esters that are freshwater biodegradable. The present application also discloses compositions, articles, beads and films (e.g. reverse dispersion quarter waveplate) made from the mixed cellulose esters.
Disclosed herein is a retrofit process to make 5-(alkoxycarbonyl)furan-2-carboxylic acids (ACFC) from feedstocks comprised of furoates. When a feedstock comprised of methyl 5-methylfuran-2-carboxylate (MMFC) is used a product comprised of (5-(methoxycarbonyl)furan-2-carboxylic acid (MCFC) is obtained in high yield.
