Abstract

The present disclosure relates to methods for producing polymers and resins, the method including a first reacting of at least a first diamine with a first carbonate-containing compound and a second carbonate-containing compound to produce at least one of the polymer or the resin, where the first reacting is according to each of R 1 , R 2 , R 3 , and R 4 include at least one of a hydrogen atom, a methyl group, a saturated hydrocarbon chain, and/or an unsaturated hydrocarbon chain, and R comprises at least one of a carbon atom, a saturated hydrocarbon chain, and/or an unsaturated hydrocarbon chain.

Claims (27)

1. A composition comprising:

a compound having the formula

and a compound having the formula

wherein:

R is derived from a naturally occurring amino acid having a carboxyl group, a first amine group, and a second amine group, and

R comprises a decarboxylated portion of the amino acid positioned between the first amine group and the second amine group,

R′ is a first hydrocarbon group,

R″ is a second hydrocarbon group,

n is between 2 and 30, inclusively, and

m is between 1 and 30, inclusively.

2. The composition of claim 1 , wherein:

R′ comprises a saturated hydrocarbon chain or an unsaturated hydrocarbon chain having between 1 and 100 carbon atoms, inclusively, and

R″ comprises a saturated hydrocarbon chain or an unsaturated hydrocarbon chain having between 1 and 100 carbon atoms, inclusively.

3. The composition of claim 1 , wherein

wherein R is

and

the symbol represents covalent bond between R and a neighboring N atom.

4. A composition comprising:

a compound having the formula

and a compound having the formula

wherein:

R is

the symbol represents a covalent bond between R and a neighboring N atom,

R′ is a first hydrocarbon group,

R″ is a second hydrocarbon group,

n is between 1 and 30, inclusively, and

m is between 1 and 30, inclusively.
