Vegetable oil , macromonomers

Apart from these direct uses as macromonomers, epoxydized vegetable oils have also been employed as precursors to other polymerizable structures, follow-... 

Copolymerisation of acrylated vegetable oil with styrene by a macromonomer (macromer) technique. 

A recent original approach to the use of vegetable oils as precursors to polyurethanes describes the ozone-induced oxidation of the single insaturations borne by each chain of canola oil triglyceride followed by the cleavage and hydroxylation of the ensuing end groups (Scheme 3.15) [110]. This triol macromonomer was then mixed... 

Vegetable oil derived macromonomers were successfully synthesized from castor, lesquerella, and vemonia oils. CAM was effectively incorporated in vinyl-acrylic and all-acrylic latexes and facilitated film formation in the absence of coalescing solvents. Lesquerella and vemonia methacrylate macromonomers were synthesized and formulated into environmentally friendly UV cured coatings. The lesquerella and vemonia modified coatings exhibited good gloss, pencil hardness, and adhesion to steel substrates. 

Soybean oil is less expensive than com, safflower, and sunflower oils. It also has a higher level of unsaturation (typical composition 53% linoleic, 21% oleic, 8% Unolenic, 10% palmitic, and 5% stearic) (Meier et al., 2(X)7) compared to some other vegetable oils. Cmde soybean oil contains approximately 95-97% triacylglycerides, making it a potential candidate as a renewable macromonomer for the polymer industry.
