Abstract

The present disclosure relates to a resin that includes a first repeat unit as defined by Structure (I) where A is either a methyl group or a hydrogen atom, R 1 is a first bridging group, and is a covalent bond.

Claims (45)

1. A resin comprising:

a first repeat unit as defined by Structure (I),

wherein:

A is selected from the group consisting of a methyl group and a hydrogen atom,

R 1 comprises a first bridging group,

and

is a covalent bond.

2. The resin of claim 1 , wherein:

R 1 comprises at least one of

and

R 2 comprises a second bridging group.

3. The resin of claim 2 , wherein:

R 2 comprises at least one of

4. The resin of claim 2 , wherein:

R 1 is

5. The resin of claim 1 , further comprising a second repeat unit as defined by Structure (II),

6. The resin of claim 1 , comprising a tensile strength between about 20 MPa and about 100 MPa.

7. The resin of claim 1 , comprising a modulus between about 0.5 GPa and about 3.0 GPa.

8. The resin of claim 1 , comprising an elongation at break between about 0.1% and about 100%.

9. The resin of claim 1 , comprising a glass transition temperature between about 0° C. and about 250° C.

10. A method comprising:

reacting a first functionalized intermediate with a second functionalized intermediate to form a resin, wherein:

the first functionalized intermediate comprises

the second functionalized intermediate comprises

the resin comprises a first repeat unit as defined by Structure (I),

the resin further comprises a second repeat unit as defined by Structure (II),

A is selected from the group consisting of a methyl group and a hydrogen atom,

R 1 comprises a first bridging group,

is a covalent bond.

11. The method of claim 10 , further comprising:

prior to the reacting, in a first mixture comprising a deconstruction product and a reactant comprising an acrylate group or a methacrylate group, functionalizing the deconstruction product, wherein:

the deconstruction product comprises

and

the functionalizing produces the first functionalized intermediate and the second functionalized intermediate.

12. The method of claim 10 , wherein:

the reacting is performed using a second mixture of the first functionalized intermediate and the second functionalized intermediate, and

the first functionalized intermediate and the second functionalized intermediate are at a molar ratio between about 1:2 and about 1:1.

13. The method of claim 12 , wherein the second mixture has a viscosity between about 800 cP and 1200 cP at when measured at a temperature of about 25° C.

14. The method of claim 10 , wherein the reacting is performed at a temperature between 20° C. and 150° C.

15. The method of claim 10 , wherein the reacting is photoinitiated at a wavelength between 254 nm and 500 nm.

16. The method of claim 10 , wherein the reacting is photoinitiated using at least one of diphenyl(2,4,6-trimethylbenzoyl)phosphine oxide (TPO), ethyl (2,4,6-trimethylbenzoyl) phenylphosphinate (TPO-L), or phenylbis(2,4,6-trimethylbenzoyl)phosphine oxide (BAPO).

17. The method of claim 11 , further comprising:

prior to the functionalizing, deconstructing a plastic, wherein:

the deconstructing results in the forming of the deconstruction product.

18. The method of claim 17 , wherein the plastic comprises at least one of polyethylene terephthalate, glycol modified polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, polyethylene naphthalate, or polyethylene 2,5-furandicarboxylate.
