LOW TEMPERATURE FLUIDITY IMPROVER FOR TRACTION DRIVE FLUID, TRACTION DRIVE FLUID COMPOSITION AND METHOD FOR MANUFACTURING LOW TEMPERATURE FLUIDITY IMPROVER

摘要

PROBLEM TO BE SOLVED: To obtain a traction drive fluid having excellent low temperature fluidity, a high coefficient of traction, and excellent practical utility. SOLUTION: The low temperature fluidity improver for traction drive fluid is made of a compound of formula [1] (wherein R1 and R2 independently represent a 1-20C hydrocarbon group provided that at least one of R1 and R2 contains a 5-20C monocyclic or bicyclic cycloalkane, R3 represents a 1-8C alkylene group, and (n) is 0, 1 or 2). The traction drive fluid composition comprises the low temperature fluidity improver.
