Abstract

The invention provides polymer compositions, compounds, processes, and methods of use of the polymers for drug delivery, biodegradable consumer plastics, or solvents for Li-based batteries or supercapacitors.

Claims (30)

1. A linear, comb, branched, or dendrite oligomer or polymer comprising the following formula:

wherein each Q′ is independently selected from among: O, S, Se, or NH;

wherein each G′ is independently is independently selected from the following structures:

and

wherein R 1 ′ is selected from among hydrogen, a straight or branched alkyl, cycloalkyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl or arylalkyl chain of 1-50 carbons, wherein each alkyl, cycloalkyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl, fluorocarbon, succinyl, or arylalkyl chain is optionally substituted internally or terminally by one or more hydroxyl, hydroxyether, carboxyl, carboxyester, carboxyamide, amino, mono- or di-substituted amino, thiol, thioester, sulfate, phosphate, phosphonate, or halogen substituents, poly(ethylene glycol), poly(ethylene oxide), poly(hydroxyacid)), a carbohydrate, a protein, a polypeptide, an amino acid, a nucleic acid, a nucleotide, a polynucleotide, any DNA or RNA segment, a lipid, a polysaccharide, an antibody, a pharmaceutical agent, or any epitope for a biological receptor, a photocrosslinkable or ionically crosslinkable group;

wherein n is selected from an integer of 1-1,000; and

wherein each polymeric terminal group is selected from among amines, thiols, amides, phosphates, sulphates, hydroxides, metals, alkanes, alkenes, and alkynes.

2. The polymer of claim 1 , wherein Q′ is O.

3. The polymer of claim 1 , wherein R′ 1 is selected from among hydrogen or a straight or branched alkyl, cycloalkyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl or arylalkyl chain of 2-50 carbons, wherein each alkyl, cycloalkyl, succinyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl or arylalkyl chain is optionally substituted internally or terminally by one or more hydroxyl, hydroxyether, carboxyl, carboxyester, carboxyamide, amino, mono- or di-substituted amino, thiol, thioester, sulfate, phosphate, phosphonate, or halogen substituents.

4. The polymer of claim 1 , wherein R′ 1 is selected from among hydrogen or a straight or branched alkyl, cycloalkyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl or arylalkyl chain of 3-50 carbons.

5. The polymer of claim 1 , wherein R′ 1 is selected from among hydrogen or a straight or branched alkyl, alkylaryl or arylalkyl chain of 3-50 carbons.

6. The polymer of claim 1 , wherein G′ is

7. The polymer of claim 6 , wherein Q′ is O.

8. The polymer of claim 6 , wherein R′ 1 is selected from among hydrogen or a straight or branched alkyl, cycloalkyl, aryl, olefin, silyl, alkylsilyl, arylsilyl, alkylaryl or arylalkyl chain of 3-50 carbons.

9. The polymer of claim 6 , wherein R′ 1 is selected from among hydrogen or a straight or branched alkyl, alkylaryl or arylalkyl chain of 3-50 carbons.

10. The polymer of claim 1 , wherein pharmaceutical agent is conjugated via a succinic acid moiety to between 5 and 95% of the available primary hydroxyl of the polymer back bone.

11. A polymeric film, sheet, mesh, foam, fiber, or particle comprising a polymer of claim 1 .

12. A composition comprising a polymer of claim 1 .

13. A biodegradable plastic for consumer goods comprising a polymer of claim 1 .

14. A copolymer or polymer blend comprising a polymer of claim 1 .

15. A cross-linked gel comprising a polymer of claim 1 .

16. A superabsorbent polymer, detergent, adhesive, dispersant, or cosmetic comprising a cross-linked gel of claim 15 .

17. A method comprising:

applying a polymeric film, sheet, mesh, foam, fiber, or particle of claim 11 to a surgical resection margin or within a treated or untreated tumor or cavity, or to target sites of disease away from the surgical margin.

18. A method comprising:

applying a polymeric film, sheet, mesh, foam, fiber, or particle of claim 11 to a tissue site, wherein the polymeric film, sheet, mesh, foam, fiber, or particle is secured to the tissue site.

19. A method comprising:

applying a polymeric film, sheet, mesh, foam, fiber, or particle of claim 11 to a surgical resection margin or within a treated or untreated tumor or cavity, or to target sites of disease away from the surgical margin; and

delivering an active agent to the surgical resection margin or the treated or untreated tumor or cavity, or the target sites of disease away from the surgical margin.

20. A method for treating cancer comprising administering a composition comprising a polymer of claim 1 and an agent to a subject in need thereof.
