Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
A METAL COMPLEX PREPARED BY THE PROCESS COMPRISING FORMING A NON-ACIDIC, ACYLATED NITROGEN INTERMEDIATE BY THE REACTION OF 1 EQUIVALENT OF A HYDROCARBON-SUBSTITUTED SUCCINIC ACID OR ANHYDRIDE HAVING AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE HYDROCARBON SUBSTITUENT WITH FROM ABOUT 1 EQUIVALENT TO ABOUT TWO MOLES OF AN AMINE SELECTED FROM THE CLASS CONSISTING OF ALKYLENE AMINES, PIPERAZINES AND IMIDAZOLINES AND REACTING SAID ACYLATED NITROGEN INTERMEDIATE WITH FROM ABOUT 0.1 EQUIVALENT TO ABOUT 2 EQUIVALENTS, PER EQUIVALENT OF THE AMINE, OF A COMPLEX-FORMING METAL COMPOUND SELECTED FROM THE CLASS CONSISTING OF NITRATES, NITRILES, HALIDES, CARBOXYLATES, PHOSPHATES, PHOSPHITES, SULFATES, SULFITES, CARBONATES, BORATES, AND OXIDES OF CADMIUM AND METALS HAVING ATOMIC NUMBERS FROM 24 TO 30 AT A TEMPERATURE ABOVE ABOUT 25*C. AND BELOW THE DECOMPOSITION POINT OF THE REACTION MIXTURE.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
107 words
A METAL COMPLEX PREPARED BY THE PROCESS COMPRISING FORMING A NON-ACIDIC, ACYLATED NITROGEN INTERMEDIATE BY THE REACTION OF 1 EQUIVALENT OF AN OLEFIN POLYMER-SUBSTITUTED SUCCINIC ACID OR APHYDRIDE HAVING AT LEAST ABOUT 50 ALIPHATIC CARBON ATOMS IN THE OLEFIN POLYMER SUBSTITUENT WITH FROM ABOUT 1 EQUIVALENT TO ABOUT TWO MOLES OF AN ETHYLENE AMINE AND REACTING SAID ACYLATED NITROGEN INTERMEDIATE WITH FROM ABOUT 0.1 EQUIVALENT TO ABOUT 2 EQUIVALENTS, PER EQUIVALENT OF THE AMINE, OF A COMPLEXFORMING METAL HALIDE IN WHICH THE METAL HAS AN ATOMIC NUMBER FROM 4 TO 30 AT A TEMPERATURE ABOVE ABOUT 25* C. AND BELOW THE DECOMPOSITION POINT OF THE REACTION MIXTURE.
