Polymers methyl ricinoleate

Heating methyl ricinoleate in excess alkali as above but at 250°C results in production of sebacic acid and 2-octanol (Hargreaves and Owen, 1947 Diamond et al., 1965). Sebacic acid, a 10-carbon dibasic acid, is used in production of polyamide 10,10 (PA10,10), a polymer with properties similar to those of PAll (Naughton, 1974 Caupin, 1997). Both PA 11 and PA 10,10 are... 

New porphyrin-containing Group IVB polymers were made using ricinoleic acid215 or hematoporphine IX.210,217,218 Polymer 93 is a representative example that was used as a selective chelating agent. Macrocyclic tetrapyrrole has four methyl, two ethanolic, and two propionic acid side chains. The polymers are cross-linked because of the four reactive functions (two acid and two alcohol groups). The adsorption of Ni+2 by porphyrin moieties was observed for the titanium polymer. 

The reaction of excess amounts of methyl acrylate and the self-metathesis products of monounsaturated fatty acids like methyl ester of oleic acid with ethylene, produces valuable monomers for polycondensation polymers, as well as precursors for detergents in the presence of a suitable metathesis catalyst. In oleochemistry, azaleic and pelargonic acid were obtained industrially by ozonolysis of oleic acid. Non-linear fatty acid derivatives with two double bonds, (ricinoleic acid maleate) and one double bond (ricinoleic acid succinate) were produced from ricinoleic acid by esterification with maleic and succinic anhydride, respectively. Hydrogenation of this ricinoleic acid succinate yielded 12-hydroxystearic acid succinate which is a monomer for vegetable oil-based polyester.
