Abstract
A NOVEL SERIES OF COPOLYMERS AND TERPOLYMERS, USEFUL AS BASE OILS FORSYNTHETIC LUBRICANTS, ARE PRODUCED BY POLYMERIZATION OF ETHYLENE, AN ALPHA-OLEFIN, AND OPTIONALLY A THIRD MONOMER COMPRISING AN ALPHA-OLEFIN OF 3 TO 20 CARBON ATOMS, IN THE PRESENCE OF A COMBINATION CATALYST COMPRISING A COMPOUND OF A TRANSITION METAL OF GROUP IVB OF THE PERIODIC TABLE AND AN ALUMINOXANE. THE COPOLYMER OR TERPOLYMER MAY BE FURTHER PROCESSED BY THERMAL CRACKING TO YIELD NOVEL CRACKED POLYMERS, AND THE CRACKED POLYMERS MAY BE HYDROGENATED. THE COPOLYMERS OR TERPOLYMERS MAY ALSO BE HYDROISOMERIZED. ALL THE POLYMERS ARE USEFUL AS BASE OILS FOR LUBRICATING OILS AND CONSUMER PRODUCTS.
