Abstract

A composition of matter, comparising: a chemically functionalized carboxylate-alumoxane that is functionalized with a chemically reactive substituent, and a reactive compound, wherein the chemically reactive substituent reacts with the reactive compound so as to link the carboxylate-alumoxnae to the reactive compound and form a polymer matrix. The functional groups on the carboxylate-alumoxane can vary depending on the desired properties of the matrix. Also, the composition of matter may comprise a cross-linked matrix in which the cross-linked components consist of functionalized alumoxanes.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A composition of matter represented by the formulae  
       [Al(O) x (OH) y (O 2 C—R—X) z ] n  and [Al(O) x (OH) y (O 2 C—R—X) z (O 2 C—R′) z′ ] n    wherein R and R′ are independently selected from the group of hydrogen and organic groups and X is a chemically reactive substituent.    
     
     
         2 . The composition of matter according to  claim 1  wherein X is selected from the group consisting of hydroxyl, amine, acrylate, vinyl and olefin.  
     
     
         3 . The composition of matter according to  claim 1  wherein X is selected from the group consisting of hydroxyl, amine, vinyl and olefin.  
     
     
         4 . The composition of matter according to  claim 1 , wherein R is an organic group and R′ is an organic group and X is selected from the group consisting of hydroxyl, amine, vinyl and olefin.  
     
     
         5 . The composition of matter according to  claim 1  wherein R and R′ are independently selected from the group consisting of alkyl, alkenyl, aromatic, haloalkyl, haloalkenyl, haloaromatic, alkyl ether, alkenyl ether and aromatic ether.  
     
     
         6 . The composition of matter according to  claim 5  wherein R and R′ are independently selected from the group consisting of alkyl, alkenyl and aromatic.  
     
     
         7 . The composition of matter according to  claim 5  wherein R and R′ are independently selected from the group consisting of haloalkyl, haloalkenyl and haloaromatic.  
     
     
         8 . The composition of matter according to  claim 5  wherein R and R′ are independently selected from the group consisting of alkyl ether, alkenyl ether and aromatic ether.  
     
     
         9 . The composition of matter according to  claim 1  wherein R and R′ are organic groups that optionally contain a heteroatom selected from the group consisting of oxygen, nitrogen, sulfur and phosphorus.  
     
     
         10 . The composition of matter according to  claim 1  wherein —R—X is 4-hydroxybenzoate.  
     
     
         11 . The composition of matter according to  claim 1  wherein —R—X is 2,6-diaminohexanoate.  
     
     
         12 . The composition of matter according to  claim 1  wherein —R—X is dimethylolpropionate.  
     
     
         13 . A composition of matter represented by the formula  
       [Al(O) x (OH) y (O 2 C—R—X) z (O 2 C—R′) z′ ] n    wherein R and R′ are independently selected from the group of hydrogen and organic groups and X is a chemically reactive substituent.    
     
     
         14 . The composition of matter according to  claim 13 , wherein R is an organic group and R′ is an organic group and X is selected from the group consisting of hydroxyl, amine, vinyl and olefin.  
     
     
         15 . The composition of matter according to  claim 13  wherein X is selected from the group consisting of hydroxyl, amine, acrylate, vinyl and olefin.  
     
     
         16 . The composition of matter according to  claim 13  wherein X is selected from the group consisting of hydroxyl, amine, vinyl and olefin.  
     
     
         17 . The composition of matter according to  claim 13  wherein R and R′ are independently selected from the group consisting of alkyl, alkenyl, aromatic, haloalkyl, haloalkenyl, haloaromatic, alkyl ether, alkenyl ether and aromatic ether.  
     
     
         18 . The composition of matter according to  claim 17  wherein R and R′ are independently selected from the group consisting of alkyl, alkenyl and aromatic.  
     
     
         19 . The composition of matter according to  claim 17  wherein R and R′ are independently selected from the group consisting of haloalkyl, haloalkenyl and haloaromatic.  
     
     
         20 . The composition of matter according to  claim 17  wherein R and R′ are independently selected from the group consisting of alkyl ether, alkenyl ether and aromatic ether.  
     
     
         21 . The composition of matter according to  claim 1  wherein R and R′ are organic groups that optionally contain a heteroatom selected from the group consisting of oxygen, nitrogen, sulfur and phosphorus.
