• The conjugated soybean oil was synthesized through the isomerization reaction of soybean oil to transformed the structure of linoleic acid into conjugated linoleic acid structure, and Rhodium complexes (RhCl(Pph 3 ) 3 ) was used as catalyst. The efficiency on the conjugation of catalyst RhCl (Pph 3 ) 3 , tin dichloride dehydrate (SnCl 2 ·2H 2 O) and triphenylphosphine (Pph 3 ) were evaluated. The results showed when RhCl(Pph 3 ) 3 , SnCl 2 ·2H 2 O and Pph 3 are 9.25, 9.0 and 13.1 mg in 100 g soybean oil respectively, the highest conversion of conjugation achieved 96%. The free radical copolymerization of conjugated soybean oil with acrylonitrile (AN) and dicyclopentadiene (DCP) was studied. AIBN was used as the initiator. FT-IR and 1 H-NMR results indicates that the conjugated soybean oil with AN and DCP did occur free radical copolymerization with the initiator AIBN. The product is light yellow powder. The thermal properties of the soy-based copolymer were investigated by TG and DSC. The initial degradation temperature of polymers is higher then 250 °C.
