Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
124 words
A composition comprising: (a) an ion exchange resin having a strongly acidic, weakly acidic, or mixed acid-base type functional group; (b) an element, selected from the transition group of elements and which is directly bonded either coordinately or ionically to the ion exchange resin; and (c) an organic linking compound of from 1 to about 100 carbon atoms which has at least one moiety selected from the group consisting of trivalent nitrogen, trivalent phosphorus, trivalent arsenic, trivalent bismuth and trivalent antimony which is coordinately bonded to said element and further has at least one moiety selected from the group consisting of monohydrocarboyl ammonium, dihydrocarbyl ammonium, trihydrocarbyl ammonium, quaternary ammonium, pyridinium, phosphinium, arsenium and sulfonium ion which is ionically bonded to the ion exchange resin.
Claim 2
Dependent Claim
