Polymers are enchantment for modern mechanized civilization because of the versatility of their applications. These materials can be tailored as per desired applications. However polymer science as a coherent subject is barely few decades old. The importance of polymers had increased because of light weight, low cost, excellent chemical resistance, anti corrosive nature and easy processbility. Polyurethane is the most versatile group of polymers next to unsaturated polyester resins. These materials are important block co-polymers. Properties of end product can be designed according to it’s application. Due to potential large volume of applications combined with high versatility in the properties, these materials require a thorough understanding of synthesis and properties as well as update of knowledge. Polyol synthesis from renewable resources and their possibility for industrial polyurethane application has gained a considerable attention in recent times.The polymer known as polyurethanes are widely used in the fields of daily life due to their excellent wear resistance, toughness, mechanical properties and chemical resistance.
