Zusammenfassung:	A copolymer which can be used in power transmission fluids to provide improved viscometric properties is disclosed. The copolymer includes a mixture of alcohols having side chains with an average number of carbons ranging from greater than 8 to less than 12 defined by the following formula: C n = i = j i = z X i C n i i = j i = z X i where X i is the mole fraction of alcohol ( i ); C ni represents the number of carbon atoms in alcohol ( i ); j is the lowest number of carbons in an alcohol in the copolymer and must be at least 6; and z is the highest number of carbons in an alcohol.
