Styrenation of triglyceride oils by macromonomer technique

A novel macromer technique is described for the styrenation of triglyceride oils. Triglyceride oil-based macromers were prepared via successive transe sterification ann condensation reactions. The macromers were styrenated at 100 degrees C using benzoyl peroxide as an initiator. The styrenation led t o improved film properties with semidrying oils. Homopolymerization of the macromonomers failed due to the stearic hindrance of the bulky oil moieties . The results obtained were also evaluated by considering the degree of uns aturation.
