Soybean Oil
“Soybean oilis a vegetable Oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils. Being one of the drying oils it is also used as a base for printing inks and oil paints.”
“100g of soybean oil has 16g of saturated fat, 23 g of mono unsaturated fat, and 58g of poly unsaturated fat.[2]The major unsaturated fatty acids in soybean oil triglycerides are 7–10% alpha-Linolenic acid (C-18:3); 51% linoleic acid (C-18:2); and 23% oleic acid (C-18:1). It also contains the saturated fatty acids 4% stearic acid and 10% palmitic acid which are long chain saturated fatty acids.”
“The high-proportion of oxidation-prone linolenic acid is undesirable for some uses, such as cooking oils in restaurants. In the early nineties, Iowa State University developed soybean oil with 1% linolenic acid. Three companies, Monsanto Company, DuPont/Bunge, and Asoyia in 2004 introduced low linolenic Roundup Ready soybeans. In the past, hydrogenation was used to reduce the unsaturation in linolenic acid, but this produced the unnatural trans-fatty acid configuration, whereas in nature the configuration is cis. This external picture from North Dakota State University compares soybean oil fatty acid content with other oils.”

Conjugation of Soybean Oil and It’s Free-Radical Copolymerization with Acrylonitrile
(189-195) Journal of Polymers and the Environment 19 #1 (2011)
Yang, Ma and Lin of South China Normal University and Guangdong University, China, synthesized conjugated soybean oil was synthesized through the isomerization reaction of soybean oil to transform the linoleic acid into conjugated linoleic acid structure, and Rhodium complexes (RhCl(Pph3)3) was used as catalyst. The conjugated soybean oil was combined with acrylonitrile (AN) and dicyclopentadiene (DCP) NS AIBN was used as the initiator. The product is light yellow powder. The initial degradation temperature of polymers is higher then 250 °C. (rdc 4/22/2011)
