Abstract: 1. PROCESS OF PREPARING A SYNTHETIC COPOLYMER OIL WHICH COMPRISES CONTACTING A MIXTURE COMPRISING ETHYLENE AND PROPYLENE IN SOLUTION OR LIQUID PHASE AT A TEMPERATURE IN THE RANGE OF 0-125*C., WITH A CATALYST SYSTEM FORMED FROM (A) AN ALUMINUM ALKYL CHLORIDE, AND (B) A COMPOUND HAVING THE FORMULA VOCL3-N(RO)0+N, WHEREIN R REPRESENTS AN ALKYL RADICAL, AND WHEREIN N HAS THE VALUE OF ZERO, ONE OR TWO, SAID ETHYLENE AND PROPYLENE BEING MAINTAINED IN THE REACTION ZONE FOR REACTION IN MONOMERIC MOL RATIO OT YIELD COPOLYMER CONTAINING 29-71 MOL PERCENT ETHYLENE, THE REST CONSISTING ESSENTIALLY OF PROPYLENE AND SAID REACTION ZONE BEING MAINTAINED UNDER HYDROGEN PARTIAL PRESSURE IN THE RANGE OF 20-2000 P.S.I.A. AND SUFFICIENTLY HIGH TO YIELD COMPOLYMER OIL HAVING A MAXIMUM AVERAGE NUMBER MOLECULAR WEIGHT OF 4000.
