Abstract

Metal-containing polymeric materials and metal complex-containing polymeric materials are provided. The polymeric materials are divinylbenzene/maleic anhydride polymers, partially hydrolyzed divinylbenzene/maleic anhydride polymers, or fully hydrolyzed divinylbenzene/maleic anhydride polymers. Additionally, methods of making the metal-containing polymeric materials, methods of using the metal-containing polymeric materials to capture volatile, basic, nitrogen-containing compounds, and methods of using a zinc-containing polymeric material to detect the presence of water vapor are provided.

First claim

We claim:

1. A metal-containing polymeric material comprising:
a) a porous polymeric material comprising
i) 15 to 65 weight percent of a first monomeric unit that is of Formula (I), Formula (II), or a mixture thereof;

ii) 30 to 85 weight percent of a second monomeric unit that is of Formula (III); and

iii) 0 to 40 weight percent (or 5 to 40 weight percent) of a third monomeric unit that is of Formula (IV)

wherein R 1 is hydrogen or alkyl; and
b) a divalent metal incorporated into the polymeric material in an amount equal to at least 1.5 mmoles per gram of the polymeric material.

2. The metal-containing polymeric material of claim 1 , wherein an amount of the divalent metal incorporated into the polymeric material is in a range of 1.5 to 15 mmoles per gram of the polymeric material.

3. The metal-containing polymeric material of claim 1 , wherein the divalent metal is from a Group 2 metal or a Group 6 to 12 metal of the IUPAC Periodic Table of Elements.

4. The metal-containing polymeric material of claim 1 , wherein the divalent metal is divalent zinc or copper.

5. The metal-containing polymeric material of claim 1 , wherein the porous polymeric material comprises i) 40 to 60 weight percent monomeric units of Formula (I), Formula (II), or a mixture thereof, ii) 30 to 55 weight percent monomeric units of Formula (III), and 5 to 20 weight percent monomeric units of Formula (IV).

6. A metal complex-containing polymeric material comprising:
a) a porous polymeric material comprising
i) 15 to 65 weight percent of a first monomeric unit that is of Formula (I), Formula (II), or a mixture thereof;

ii) 30 to 85 weight percent of a second monomeric unit that is of Formula (III); and

iii) 0 to 40 weight percent (or 5 to 40 weight percent) of a third monomeric unit that is of Formula (IV)

wherein R 1 is hydrogen or alkyl; and
b) a metal complex incorporated into the polymeric material, wherein the metal complex comprises a reaction product of
i) a divalent metal; and
ii) at least one basic, nitrogen-containing compound.

7. The metal complex-containing polymeric material of claim 6 , wherein metal complex-containing polymeric material further comprises divalent metal that is not in the form of the metal complex.

8. The metal complex-containing polymeric material of claim 6 , wherein a total amount of divalent metal is in a range of 1.5 to 15 mmoles per gram of the polymeric material.

9. The metal complex-containing polymeric material of claim 6 , wherein the at least one basic, nitrogen-containing compound has a molecular weight no greater than 150 grams/mole.

10. The metal complex-containing polymeric material of claim 6 , wherein the at least one basic, nitrogen-containing compound is ammonia, a hydrazine compound, an amine compound, or a nitrogen-containing heterocyclic compound.

11. A method of capturing a basic, nitrogen-containing compound, the method comprising:
providing a metal-containing polymeric material according to claim 1 ; and
exposing the metal-containing polymeric material to a basic, nitrogen-containing compound to form a metal complex-containing polymeric material.

12. The method of claim 11 , wherein the metal-containing polymeric material changes color upon exposing the metal-containing polymeric material to the basic, nitrogen-containing compound.

13. The method of claim 11 , wherein a total amount of divalent metal is in a range of 1.5 to 15 mmoles per gram of the polymeric material.

14. The method of claim 11 , wherein the compound of formula Q has a molecular weight no greater than 150 grams/mole.

15. The method of claim 11 , wherein the metal-containing polymeric material sorbs an amount of the basic, nitrogen-containing compound in a range of 0.5 to 10 milliequivalents per gram of the metal-containing polymeric material.
