Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
A POLYMER HAVING AN INORGANIC BACKBONE CONSISTING OF A DOUBLY BRIDGED, TRIVALENT, OCTAHEDRAL METAL COORDINATED WITH TWO UNIDENATE LIGANDS WHEREIN EACH OF SAID BRIDGING GROUPS IS THE ANION OF AN ACID R2M''(O)OH WHERE R IS ALKYL, ARYL, ALKYLOXY OR ARYLOXY, M'' IS AN ELEMENT SELECTED FROM GROUP VB HAVING AN ATOMIC NUMBER GREATER THAN 7, AND WHEREIN ONE OF SAID UNIDENTATE LIGANDS IS A NEGATIVE MONOVALENT ION AND THE SECOND UNIDENTATE LIGAND IS A NEUTRAL MOLECULE SELECTED FROM THE GROUP CONSISTING OF WATER AND AMMONIA.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
98 words
THE PROCESS OF REACTING A DIVALENT METAL SALT HAVING A COORDINATION NUMBER OF SIX IN ITS TRIVALENT STATE WITH AN ACID ANION OF STRUCTURE R2M''(O)O- WHERE R IS A MEMBER OF THE GROUP CONSISTING OF HYDROCARBON ALKYL AND ARYL CONTAINING FROM ONE TO TEN CARBON ATOMS, AND M'' IS AN ELEMENT SELECTED FROM GROUP VB HAVING AN ATOMIC NUMBER GREATER THAN SEVEN AND THEREAFTER OXIDIZING THE METAL IN THE PRODUCT TO THE TRIVALENT OXIDATION STATE, SAID OXIDATION OCCURRING IN THE PRESENCE OF A NUETRAL LIGAND SELECTED FROM THE GROUP CONSISTING OF WATER AND AMMONIA AND A UNIVALENT LIGAND.
