FLUID FOR IMPROVED TRACTION

摘要

PURPOSE:To provide the titled relatively inexpensive fluid giving high coefficient of traction, comprising a both cyclohexyl ring and chain hydrocarbon-bound ester compound (derivative) and hydrocarbon polymer. CONSTITUTION:The objective fluid comprising 0.1-95(pref. 10-70)wt% of (A) an ester (derivative) of formula (A' is -COO- or -OOC-; n is 1-14; R1 is H or 1-8C alkyl; R2 is H or 1-3C alkyl) plus (B) a hydrocarbon polymer (pref. polybutene) or ester polymer.
