Sesame oil/succinic acid/tiricinolein copolymer means a polymer obtained by transesterification of Sesamum Indicum (sesame) oil with succinicacid and triricinolein (1,2,3-propanetriyltri(12-hydroxy-9(Z)-octadecenoate). "Copolymer" means a polymer composed of several different (usually two) basic units (monomers).
