    Abstract: Disclosed is an oxyalkylene-modified polyoxybutylene alcohol having an improved viscosity index. Notably enhancement of the viscosity index is obtained when the polyoxybutylene alcohol contains an internal oxypropylene or oxyethylene block; and wherein the total amount of converted butylene oxide in the molecule is from 99 to 75 parts per 100 parts by weight of the total converted alkylene oxide.
