Linoleic acid, cellulose ester

Perilla oil p9- ri-l9 (1917) n. A drying oil obtained from the seed of the perilla plants, Perilla ocymoides and Perilla nankinensis, natives of the Orient. Its main constituent acids are linoleic and linolenic, and it has the highest iodine value of all known vegetable oils except chia. It is superior to linseed oil, both from the point of view of drying rate, especially in the form of stand oil, and also of polymerization rate. Sp gr, 0.933-0.937 per 15°C iodine value, 194, saponification value, 192. Paint pigment, drying oils, polymers, resins, naval stores, cellulosics esters, and ink vehicles, vol 3. American Society for Testing and Material, Philadelphia, PA, 2001. 

Tall oil heads (light ends) n. Low-boihng fractions obtained by the fractional distillation of crude tall oil under reduced pressure. The composition of these products varies over a wide range but contains palmitic, oleic, linoleic, and stearic acids together with lesser amounts of other saturated and unsaturated fatty acids. The neutral materials content is normally high. Paint pigment, drying oils, polymers, resins, naval stores, cellulosics esters, and... 

Esters of unsaturated acids are of experimental interest because of their ability to be converted into insoluble products. Cellulose crotonate, upon heating in the presence of air, or upon exposure to ultraviolet light, becomes completely insoluble. This action may be accelerated by the addition of small quantities of benzoyl peroxide. Esters of more active unsaturated acids, such as cellulose acetate linoleate, become insoluble upon exposure to air at ordinary temperatures. ...
