    Bio-based polymeric materials from renewable resources are significantly important in industrial and economic viewpoints. Inexpensive triglyceride plant oils have been used for production of valuable resins. However, these oil-based polymeric materials do not show enough properties of rigidity and strength required for structural applications by themselves. In this account, new crosslinkable polyphenols were designed on the basis of model “urushi” and synthesized by the oxidative polymerization of urushiol analogues, phenol derivatives bearing an unsaturated group. Furthermore, bio-based composite materials from renewable natural oils have been developed. By selected combination of natural oil and additives, the properties of the oil-based polymers were significantly improved.

    Polyhydroxyalkanoates (PHAs) are thermoplastics which accumulated in the bodies of many kinds of bacteria, and various applications are expected as environmentally friendly type plastics, because they are biodegraded to water and carbon dioxide by bacteria in the environment. PHBH is a kind of PHAs which consists of 3-hydroxybutanoic acid (3HB) and 3-hydroxyhexanoic acid (3HH), and is produced by bacteria using plant oils or fatty acids as a carbon source. PHBH is expected that it is possible to apply to various fields, because it indicates wide properties according to the 3HH monomer ratio, and we have studied commercial production technologies and the processing technologies.

    Rilsan®, Polyamide-11 (PA11) is a high performance polyamide produced from amino-11, a monomer derived from castor oil, a non edible and renewable resource. PA11 has been trusted in critical safety and performance applications for over 50 years. Capitalizing on its long-standing experience in castor oil chemistry, Arkema has now developed several range of high performance biobased products based on PA11 monomer, such as Pebax® Rnew-polyamide elastomer, Rilsan® Clear Rnew-transparent polyamide, Rilsan® HT-high temperature flexible polyamide and Platamid® Rnew-hotmelt adhesive. Not only from environmental point of view, but also their impressive performances offer new concept for final product. The present paper deals with the performance of new polyamides derived from castor oil and their application in the market.
