“…The peaks of -HNCOOCH2-are observed at 4.1-3.9ppm and for CH3 of TDI appear at 2.25ppm. 13 The thermal degradation of PFADU was observed at 177 o C and 357 o C, with 5% weight loss occurring at 200 o C attributed to the entrapped solvent and moisture, 10wt% loss at 225 o C, attributed to the decomposition of urethane moieties, 50wt% and 80wt% losses at 390 o C and 455 o C, respectively, attributed to the degradation of the aromatic ring and aliphatic pendant fatty alkyl chains, respectively.…”

“…Today, several environment friendly routes for the production of PU have cropped up. Research has been focussed on the preparation of PU from non-isocyanate routes, and also on the use of fatty acid based isocyanates for PU production, considering the persisting challenges of polymer industry and immediate attention sought towards environmentally benign chemicals and chemical routes for the same [9][10][11][12][13][14][15][16][17][18].…”

In the article is given a review on synthesis and application nonisocyanate polyurethanes based on cyclic carbonate oligomers. Nonisocyanate polyurethane (NIPU) networks are obtained by reaction between the polycyclic carbonate oligomers and aliphatic or cycloaliphatic polyamines with primary amino groups. This forms a crosslinked polymer with -hydroxyurethane groups of different structure -polyhydroxyurethane polymer. One of the most interesting derivatives of unsaturated fatty compounds is epoxidized triglyceride oils (ETO), particulary epoxidized soybean oil (ESBO). Until now, ESBO is primarily used as plasticizers for polyvinyl chloride, chlorinated rubber and polyvinyl emulsions to improve their stability and flexibility. Also there are numerous useful derivatives of ETO. Among the various materials, products of reactions of ETO and carbon dioxide (CO 2 ) deserve special attention. A basic composition and a technique for mixing and foaming were developed for insulating foam applied by spraying, the material being based on the use of the synthetic raw materials. UV-curable concrete floor coatings provide a durable, high-performance and eco-friendly solution. These thin-film coating systems cure instantly, thereby minimizing the downtime of any facility. Other benefits of these coatings include excellent chemical resistance, easy cleanability, little odor, and the ability to coat in cold conditions; Fig. 3

Vegetable oils, fish oil and oils from algae are excellent raw materials for new polymers. These oils differ in the structure and unsaturation, but each offer specific advantages. Vegetable oils are inexpensive and offer different degrees of unsaturation. Fish oils may have a very high degree of unsaturation. Algal oils are new raw materials with still unexplored possibilities. Most oils are triglycerides but cashew nut oil is an aromatic compound with a long hydrocarbon chain. Direct polymerization of oils has been used in coatings for a long time. Oils can be thermally polymerized by heating at a high temperature. The products are oligomers of high viscosity. We have developed a method for cationic polymerization of oils at mild conditions, useful as lubricants and modifiers for rubber, asphalt etc. However, for high strength materials, it is necessary to introduce functional groups such are hydroxyls, carboxyls, amine etc. Hydroxyls are the most useful ones, since they open the whole area of polyurethanes (foams, coatings, adhesives, elastomers and sealants). One can utilize the triglyceride structure or to use fatty acid derivatives, opening a wide field of combinations to suit different material requirements. This presentation will give a cross-section of different possibilities for creation of new materials from the biological oils.
