    The invention is concerned with an anhydrous oily lubricant, which is based on vegetable oils, which is substituted for mineral lubricant oils, and which, as its main component, contains triglycerides that are esters of saturated and/or unsaturated straight-chained C10 to C22 fatty acids and glycerol. The lubricant is characterized in that it contains at least 70 percent by weight of a triglyceride whose iodine number is at least 50 and no more than 125 and whose viscosity index is at least 190. As its basic component, instead of or along with the said triglyceride, the lubricant oil may also contain a polymer prepared by hot-polymerization out of the said triglyceride or out of a corresponding triglyceride. As additives, the lubricant oil may contain solvents, fatty-acid derivatives, in particular their metal salts, organic or inorganic, natural or synthetic polymers, and customary additives for lubricants.

    Different carbon-oxygen and carbon-carbon bridging bonds are formed, and the products obtained are more easily dissolved in hydrocarbons. However, the lubricating oil films produced from them are less durable than those made from hot polymerized oil.
    Polymerization in the absence of oxygen usually takes place at 312 ° C.
    Example 1 A variety of base oils are prepared by dissolving various amounts of oleic acid methyl ester in rapeseed oil. For each oil in the specified range, the viscosity is determined at two temperatures. By pour point is meant the lower temperature at which the oil is still in a liquid state for 24 hours. A number of the oils listed in Table 2 are obtained. four.

    PRI me R 4. Resistance to the load of lubricating oil based on rapeseed oil, compared with lubricating oils based on oil. The comparison is carried out using equipment according to the standard of Sweden, mounted on a chain saw blade. The radius of the tip of the tooth head of the blade is 28 mm and there is no wheel with which the tooth tip engages, and at the top there is a sliding contact between the blade and the saw chain, It uses a chain of brand 50 AC 54 E Oregon, which leads to two electric motor with a speed of 17 m / s. The surface pressure between the chain and the web is controlled by changing the web load with the help of appropriate weights. The chain lubricating oil is supplied to the web through the lubrication hole with a pump at a flow rate of 6 ml / min. During testing by the Institute, the temperature of the edge of the saw blade is measured as a function of the load. The oils used for comparison are conventional oils used for lubricating chains.
