Renewable polymers and resins and methods of making the same
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
exact text as granted — not AI-modified1 - 20 . (canceled)
21 . A method for producing a petroleum-derived or biomass-derived polymer or resin without the use of an isocyanate comprising reacting a polyamine and a carbonated lipid.
22 . The method of claim 21 wherein the polyamine is a diamine.
23 . The method of claim 22 wherein the diamine is derived from a decarboxylated amino acid.
24 . The method of claim 22 wherein the diamine has the formula:
wherein R is a functionalized or unfunctionalized alkylene and R′ is an amino acid side chain.
25 . The method of claim 24 wherein the amino acid is derived from agricultural waste.
26 . The method of claim 24 wherein the amino acid is derived from microalgae
27 . The method of claim 21 wherein the carbonated lipid is a triglyceride, diglyceride, monoglyceride, or a fatty acid, each having two or more carbonate groups.
28 . The method of claim 21 wherein the carbonated lipid is obtained from an unsaturated lipid.
29 . The method of claim 28 wherein the carbonated lipid is produced by deoxygenating a saturated lipid to form an unsaturated lipid and carbonating the unsaturated lipid.
30 . The method of claim 28 wherein the carbonated lipid is produced by epoxidizing an unsaturated lipid.
31 . The method of claim 30 further comprising the step of isolating the unsaturated lipid from a crude oil via electrophoresis.
32 . The method of claim 31 wherein the unsaturated lipid is obtained from biomass.
33 . The method of claim 31 wherein the crude oil is obtained from algae.
34 . The method of claim 29 wherein the deoxygenating step is conducted with a shape selective catalyst or a microporous catalyst.
35 . The method of claim 21 wherein the polyamine is cadaverine.
36 . The method of claim 21 wherein the polyamine is tyrosine-cadaverine diamide.
37 . The method of claim 21 wherein the carbonated lipid is carbonated soybean oil.
38 . The method of claim 21 wherein the polyamine and the carbonated lipid are derived from a biomass, wherein the process further comprises the steps of:
a. obtaining a biomass,
b. separating an amino acid mixture from the biomass;
c. separating a lipid mixture from the biomass;
d. isolating one or more amino acids from the amino acid mixture;
e. optionally decarboxylating one or more amino acids in the amino acid mixture and/or reacting one or more amino acids with a diamine to form the polyamine;
f. deoxygenating the lipid mixture to form an unsaturated lipid;
g. epoxidizing the unsaturated lipid to form an epoxidized lipid; and
h. converting the epoxidized lipid to the carbonated lipid.
39 . The method of claim 21 the polyamine and carbonated lipid are heated.
40 . The method of claim 39 wherein the polymer or resin is cured under a vacuum.Join the waitlist — get patent alerts
