Polymer engineering is an engineering field that designs, analyses, or modifies polymer materials. A polymer is a large molecule or a macro molecule which essentially is a combination of many sub units. The term polymer in Greek means ‘many parts’. Polymers are all created by the process of polymerization wherein their constituent elements referred to as monomers, square measure reacted together to form polymer chains i.e 3-dimensional networks forming the polymer bonds. Materials of Engineering refers to choosing the proper materials for the application in which the built part is being used. This selection process includes choosing the material, taking note to its specific sort or grade based on the required properties.
