Polyamides from terpenes: Amorphous Caramid-R and semi-crystalline Caramid-S
(PHYSorg.com Chemistry)

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB has developed a sustainable alternative to petrochemically produced plastics using terpenes found in resin-rich wood. The natural substances are available from conifers such as pine, larch or spruce. In the production of pulp, in which wood is broken down to separate the cellulose fibers, the terpenes are isolated in large quantities as a by-product, turpentine oil.
