Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
106 words
A PROCESS FOR THE PRODUCTION OF POLYMERS OF POLYMERIZABLE OLEFINS HAVING TWO TO EIGHT CARBON ATOMS AND ONE TO TWO TERMINAL OLEFINIC DOUBLE BONDS WHICH COMPRISES BRINGING THE OLEFIN INTO CONTACT WITH A MIXTURE CONSISTING ESSENTIALLY OF (A) A METAL CHELATE COMPOUND OF AT LEAST ONE METAL SELECTED FROM GROUPS, IB, IIB, IVA, VA, VB, VIB, VIIB AND VIII OF THE PERIODIC SYSTEMS AND THE RARE EARTHS AND A MEMBER SELECTED FROM THE GROUP CONSISTING OF B-DIKETONES, B-KETOCARBOXYLIC ESTERS, AMINOACIDS HAVING TWO TO TEN CARBON ATOMS, SALICYLALDEHYDE, O-AMINOPHENOL AND 4,5-PHENANTHROLINE AND (B) A CYCLIC UNSATURATED ALIPHATIC HYDROCARBON HAVING FIVE TO TWELVE CARBON ATOMS IN THE RING.
Claim 2
Dependent Claim
