Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
98 words
A METHOD FOR DEACTIVATION AND AGGLOMERATION OF METALLIC CATALYST RESIDUES FROM A POLYMERIZATION REACTION MIXTURE WHEREIN THE POLYMER IS SUBSTANTIALLY IN SOLUTION AND IN WHICH THE CATALYST COMPRISES AT LEAST TWO COMPONENTS, (1) A COCATALYST AND (2) A CATALYST, AT LEAST ONE COMPONENT OF WHICH PRODUCES METALLIC RESIDUES, AND THE RESULTING POLYMERIZATION REACTION MIXTURE CONTAINS POLYMER FROM AT LEAST ONE OLEFINIC REACTANT, WHICH CONSISTS OF ADDING THERETO AN ORGANIC PEROXIDE, AS THE SOLE DEACTIVATING AND AGGLOMERATING AGENT, IN AN AMOUNT SUFFICIENT TO EFFECTIVELY DEACTIVATE AND AGGLOMERATE ALL METALLIC CATALYST RESIDUES, AND SEPARATING THE DEACTIVATED, AGGLOMERATED CATALYST RESIDUES THEREFROM.
Claim 2
Independent Claim
98 words
A METHOD FOR DEACTIVATION AND AGGLOMERATION OF METALLIC CATALYST RESIDUES FROM A POLYMERIZATION REACTION MIXTURE WHEREIN THE POLYMER IS SUBSTANTIALLY IN SOLUTION AND IN WHICH THE CATALYST COMPRISES AT LEAST TWO COMPONENTS, (1) A COCATALYST AND (2) A CATALYST, AT LEAST ONE COMPONENT OF WHICH PRODUCES METALLIC RESIDUES, AND THE RESULTING POLYMERIZATION REACTION MIXTURE CONTAINS POLYMER FROM AT LEAST ONE OLEFINIC REACTANT, WHICH CONSISTS OF ADDING THERETO AN ORGANIC PEROXIDE, AS THE SOLE DEACTIVATING AND AGGLOMERATING AGENT, IN AN AMOUNT SUFFICIENT TO EFFECTIVELY DEACTIVATE AND AGGLOMERATE ALL METALLIC CATALYST RESIDUES, AND SEPARATING THE DEACTIVATED, AGGLOMERATED CATALYST RESIDUES THEREFROM.
Claim 3
Independent Claim
120 words
A METHOD FOR DEACTIVATION AND AGGLOMERATION OF METALLIC CATALYST RESIDUES FROM A POLYMERIZATION REACTION MIXTURE WHEREIN THE POLYMER IS SUBSTANTIALLY IN SOLUTION AND IN WHICH THE CATALYST COMPRISES AT LEAST TWO COMPONENTS, (1) A COCATALYST AND (2) A CATALYST, AT LEAST ONE COMPONENT OF WHICH PRODUCES METALLIC RESIDUES, AND THE RESULTING POLYMERIZATION REACTION MIXTURE CONTAINS POLYMER FROM AT LEAST ONE OLEFINIC REACTANT, WHICH CONSISTS OF ADDING THERETO AN ORGANIC PEROXIDE, IN AN AMOUNT BETWEEN 100 AND 500 WEIGHT PERCENT OF TOTAL CATALYST, AND HYDROGEN PEROXIDE, IN AN AMOUNT BETWEEN 2 AND 5 WEIGHT PERCENT OF TOTAL CATALYST, SAID PEROXIDES BEING THE SOLE DEACTIVATING AND AGGLOMERATING AGENTS, AND SEPARATING THE DEACTIVATED, AGGLOMERATED CATALYST RESIDUES FROM THE THUS TREATED POLYMERIZATION REACTION MIXTURE.
