In the field of film-forming materials, use of alkyd resins incorporating plant oils or their derivatives has been a standard practice for a century, but no major qualitative advance was introduced imtil recently. The same applies for bulk polymers based on vegetable oils, of which linoleum (first commercialised in the middle of the 19 century) was for a long time the only important representative of these materials. Nylon 11 (commercialised under the name of Rilsan based on castor oil as a precursor) has been an important addition to this small family from the 1950s onwards. In other words, vegetable oils represented a very modest presence as basic constituents of macromolecular materials up to about a decade ago, but the situation has evolved radically since then.
