摘要： PROBLEM TO BE SOLVED: To obtain a lubricating additive which prevents the degradation in lubricating performance of a gas oil due to its low sulfur content by using an ester of an aliph. hydroxycarboxylic acid having a specified number of carbon atoms with an aliph. carboxylic acid as the additive. SOLUTION: An ester of a 2-30C aliph. hydroxycarboxylic acid of formula I with an 8-22C aliph. carboxylic acid of formula II is used. In the formulas, R1 is 1-29C alkyl or alkenyl having at least one hydroxyl group; R2 is 7-21C alkyl or alkenyl; and n is 1 or 2. A condensate of the hydroxycarboxylic acid of formula I may be used in place of the hydroxycarboxylic acid. An ester of the above-mentioned ester with a 1-10C aliph. alcohol can also be used. This additive, in an amt. of 0.001-0.05 wt.%, is added to a low-sulfur gas oil having a sulfur content of 0. 05 wt.% or lower.

摘要： PROBLEM TO BE SOLVED: To provide a high-molecular aliph. polyester improved in biodegradability by polycondensing an α, ω-aliph. dicarboxylic acid (anhydride) with an α, ω-aliph. diol, and mutually linking the molecules of the resulting prim. polyester with a specific glycidyl ether compd. SOLUTION: An α,ω-aliph. dicarboxylic acid (anhydride) (A) is polycondensed with an α,ω-aliph. diol (B) to obtain a prim. polyester. 100 pts.wt. prim. polyester is heat melted at 130 to 170 deg.C. The molten polyester is then reacted with 0.1-5 pts.wt. glycidyl ether compd. having at least two glycidyl groups to mutually link the molecules of the prim. polyester with the glycidyl ether compd. to thereby obtain an aliph. polyester in the form of a sec. polyester having a wt.-average mol.wt. of 8,000 to 5000,000, and comprising polyester blocks having a wt.-average mol.wt. of 3,000 to 100,000 and obtd. by polycondensation of the component (A) with the component (B) and ether segments having ether bonds in each main chain thereof for mutually linking the polyester blocks.
