Kundu Department of Chemical Technology, Sant Longowal Institute of Engineering and Technology, Sangrur, Punjab 148106, India Received 23 January 2006; received in revised form 14 September 2006; accepted 15 September 2006 Abstract Emerging technological knowledge is leading research into new ventures. One such is the conversion of natural oils to polymers to augment the use of petroleum products as the source of polymeric raw materials. Natural oils, such as vegetable oils, now mainly used in the food industry, offer alternatives, and recent research has studied new routes of synthesis of polymers from natural oils. This review paper discusses the synthesis and characterization of new polymers from different natural oils such as soybean, corn, tung, linseed, castor, and fish oil. The effects of different levels of unsaturation in the natural oils and various types of catalysts and comonomers on the properties of copolymers are considered. r 2006 Elsevier Ltd.
