Abstract

Polymers, including Polyesters and Polycarbonates comprising residue of bis-furan diol, which is produced from renewable furfural feedstock and methods of making and using of those polyesters and polycarbonates are described. The method includes reacting a bis-furan diol with a dicarboxylic acid in the presence of a carbodiimide to produce the bis-furan containing polymers. In certain embodiments, the dicarboxylic acid is succinic acid; the bis-furan diol is the 5,5′-(propane-2,2-diyl)bis(furan-2,5-diyl) dimethanol and the carbodiimide is of N,N-diisopropylcarbodiimide.

First claim

What is claimed is:

1. A composition comprising Formula I:

wherein:
R is C 6 H 4 or (CH 2 ) x , wherein x is from 1 to 10; and
n is from 10 to 10,000;

and salts, stereoisomers, polymorphs, racemates, solvates, and hydrates thereof.

2. The composition of claim 1 , wherein the composition comprises monomeric units having a structural formula of Formula II:

3. The composition of claim 1 , wherein the composition comprises Formula III:

wherein n is from 10 to 10,000.

4. The composition of claim 1 , wherein the composition comprises Formula IV:

wherein n is from 10 to 10,000.

5. A composition comprising Formula VI:

wherein n is from 10 to 10,000;
and salts, stereoisomers, polymorphs, racemates, solvates, and hydrates thereof.
