Abstract
Compounds derived from biomass, e.g., cellulose and lignins, methods of forming such compounds and polymers and products formed using such compounds.
Claims31
A compound according to formula II:
- wherein both G′ and CT′ are independently
- and where a is 1, 2 or 3;
- and b and c are independently 0, 1, 2, or 3.
A compound according to formula II:
- wherein one of G1 and G2 is —(CH2)dOH, wherein d is 1, 2, 3, 4 or 5, and the other of G1 and G2 is
- where a is 1, 2 or 3;
- and b and c are independently 0, 1, 2, or 3,
- —(CH2)dOH where d is 1, 2, 3, 4 or 5, or
- —(CH2)eCOOH where e is 0, 1, 2, 3, 4 or 5.
2 more elements
A compound according to formula II:
- wherein both G1 and G2 are independently —(CH2)eCOOH where e is 0, 1, 2, 3, 4 or 5,
- with the caveat that if both G1 and G2 are —(CH2)eCOOH and one of e is 2 then the other e is not 0 or 2 and with the caveat that the compound according to formula II is asymmetric.
