Polyolefinic oils obtained from olefin oligomerization or copolymerization involve the most common synthetic hydrocarbon oils. Research and experimental results concerning high viscosity index synthetic polyolefinic oils and viscosity index improvers' production by ethylene–propylene copolymer (EPR) and thermal destruction of EPRs noted for various molecular weight and composition resulted in high viscosity index polyolefinic oils and thickeners. The effect of structure, composition, and molecular weight on the destruction process has been discussed for various EPRs. The resulting polyolefinic oils and viscosity index improvers were studied. © 1992 John Wiley & Sons, Inc.
