<p>A compsn. comprises: (A) a triglyceride estolide of formula (I), where R1 is aliphatic gp. opt. contg. ester moiety R2COO-, at least one R1 being an aliphatic gp. contg. the ester moiety and contg. 5-23C, and R2 = 1-100C hydrocarbyl; and (B) at least one animal fat, vegetable oil or synthetic triglyceride oil of formula (II), where R3, R4 and R5 each = 1-23C aliphatic gp. opt. contg. hydroxy and which are at least 60% mono-unsatd., and where the oleic acid moiety:linoleic acid moiety ratio is 2-90. The triglyceride is a vegetable oil triglyceride. R3, R4 and R5 each have 5-23C, pref. 11-21C. The triglyceride is sunflower oil, safflower oil, corn oil, soybean oil, rapeseed oil, meadowfoam oil, lesquerella oil, castro oil opt. genetically modified. The triglyceride has at least 70% mono-unsaturation is a residue of oleic acid. One R1 is 9-19C aliphatic gp. and the other R1 are gps. of formula (III), where R2 = 1-23C aliphatic gp., pref. heptadecenyl or isostearyl, and n=5-13. (A) is an estolide or lesquerella oil opt. genetically modified. The wt. ratio of (A):(B) is (1-99):(99-1). The compsn. opt. uses (C) an acidic, enzymic or basic catalyst. (A) is prepd. by reacting a triglyceride with a carboxylic acid or esters thereof, pref. fumaric acid.</p> |
