PURPOSE:To obtain a new composition suitable as grease, engine oil, etc., satisfying high lubricating performances and appearance of light color, containing a cured material prepared by crosslinking a specific ratio of vinyl type double bond of polybutadiene as an essential component. CONSTITUTION:The objective composition containing a cured material prepared by crosslinking >=10% (most preferably >=90%) vinyl type double bond of polybutadiene having >=20mol% (most preferably >=60mol%) based on monomer unit of vinyl type double bond, as an essential component. Hydraulic oil, gear oil, bearing oil, etc., may be cited as use of the composition besides the uses of the purpose. |
