The reviewed work addressed the shift in focus from conventional polymers to bio-based and renewable polymers. This chapter reviews the most important aspects of the application of click chemistry reactions in polymer science. The click chemistry approaches have revolutionized the polymer chemistry allowing the preparation of a wide range of functional polymers and complex macromolecules as well as facilitating the surface modification of diverse polymeric materials. Concisely, click chemistry encompasses a group of reactions that are fast, efficient, selective, tolerance to a variety of solvents and functionalities, and give high yields. "Click" reactions include several kinds of selective and orthogonal chemical ligations with high efficiency under mild reaction conditions. Different oils including grape, palm, sunflower, sesame, maize, olive etc are collected and have been used for analysis using conventional methods and further by FTNIR, FTIR. The collected spectral data from both NIR &IR are used for development of multivariate methods using unscrambler. This paper focuses on review of a work carried out by researchers in the field of production of biopolymers from different types of oil. This review paper contains the work of past researchers published between 2005 and 2015.
