PURPOSE:To provide a novel solid lubricant comprising the fluorinated product of cured product prepared by subjecting the vinyl type bonds of a specific polybutadiene to a crosslinking reaction, capable of imparting high lubricity in a small amount and having a pale color. CONSTITUTION:The objective solid lubricant comprises a product prepared by treating a cured product with a fluorination agent such as fluorine gas, the cured product being prepared by crosslinking >=10mol% (optimally >=90mol%) of the vinylic double bonds of polybutadiene which contains the vinylic bonds in an amount of >=20mol% based on the monomer units thereof and has an average mol.wt. of 500-100000 (optimally 1500-8000). The lubricant can be compounded with lubricating base oils, synthetic resins, rubbers, etc. |
