Abstract

Degradable polycarbonates network based bulk materials are provided. The bulk materials of the present disclosure may be produced having a wide range of tunable mechanical, physical, and thermal properties and are hydrolytically degradable. The bulk materials of the present disclosure may be suitable for the manufacture of a variety of sport fishing equipment or other equipment for water use or that may benefit from hydrolytic degradation in the environment.

First claim

What is claimed is:

1. A hydrolytically-degradable device comprising a hydrolytically-degradable polycarbonate network, wherein the hydrolytically-degradable polycarbonate network comprises:
a polyhydroxyl monomer that is a natural product, wherein at least one hydroxyl group of the polyhydroxyl monomer is modified with an allyl carbonate group, or any mixtures thereof;
a crosslinking comonomer; and
a functional additive.

2. The device of claim 1 , wherein the polyhydroxyl monomer is a molecule comprising two or more hydroxyl groups.

3. The device of claim 1 , wherein the polyhydroxyl monomer modified with an allyl carbonate group is an allyl glucopyranoside monomer.

4. The device of claim 1 , wherein the polyhydroxyl monomer modified with an allyl carbonate group is an allyl sucrose monomer.

5. The device of claim 1 , wherein the crosslinking comonomer is a thiol comonomer.

6. The device of claim 1 , wherein the polycarbonate network has a glass transition temperature in the range of from −25° C. to 175° C.

7. The device of claim 1 , wherein the polycarbonate network has a storage modulus in the range of from 0.1 MPa to 4000 MPa.

8. The device of claim 1 , wherein the functional additive is selected from the group consisting of glitters, dyes, fragrances, flavorants, insect repellents, photoacid generators, pH sensitive moieties, plasticizers, tougheners, and any combination thereof.

9. A hydrolytically-degradable device comprising:
a bulk material comprising:
a polyhydroxyl monomer that is a natural product, wherein at least one hydroxyl group of the polyhydroxyl monomer is modified with an allyl carbonate group, or any mixtures thereof;
a crosslinking comonomer; and
a functional additive.

10. The device of claim 9 , wherein the bulk material is a film or pellet.

11. The device of claim 9 , wherein the polyhydroxyl monomer is a molecule comprising two or more hydroxyl groups.

12. The device of claim 9 , wherein the polyhydroxyl monomer comprises an allyl glucopyranoside monomer.

13. The device of claim 9 , wherein the polyhydroxyl monomer comprises an allyl sucrose monomer.

14. The device of claim 9 , wherein the crosslinking comonomer is a thiol comonomer.

15. The device of claim 9 , wherein the polycarbonate network has a glass transition temperature value in the range of from −25° C. to 75° C.

16. The device of claim 9 , wherein the polycarbonate network has a storage modulus value in the range of from 0.1 MPa to 4000 MPa.

17. The device of claim 9 , wherein the functional additive is selected from the group consisting of glitters, dyes, fragrances, flavorants, insect repellents, photoacid generators, sensitive moieties, plasticizers, tougheners, and any combination thereof.

18. A method comprising:
providing a plurality of polyhydroxyl monomers that are natural products, wherein at least one hydroxyl group of each of the plurality of polyhydroxyl monomers is modified with an allyl carbonate group, or any mixtures thereof, a plurality of crosslinking monomers, and a functional additive;
mixing the polyhydroxyl monomers, the plurality of crosslinking monomers, and the functional additive to form a resin;
curing the resin to form a bulk material; and
making a hydrolytically-degradable device that encounters an aqueous environment and degrades a set time thereafter.

19. The method of claim 18 , wherein curing the resin to form a bulk material further comprises crosslinking the resin.

20. The method of claim 18 , wherein curing the resin to form a bulk material further comprises irradiating the resin using UV light.

21. The method of claim 18 , wherein curing the resin to form a bulk material further comprises heating the resin.

22. The method of claim 18 , further comprising controlling at least one mechanical or physical property of the bulk material.

23. The method of claim 22 , wherein at least one mechanical or physical property comprises a glass transition temperature value or a storage modulus value.
