Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new copolymer that is used in power transmission fluid to provide improved viscometric properties. SOLUTION: The copolymer that is used in power transmission fluid 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 formula: wherein Xiis the molar fraction of alcohol (i); Cnirepresents the number of carbon atoms in the 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.
