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 called monomers, are reacted together to form polymer chains i.e 3-dimensional networks forming the polymer bonds. Materials of Engineering refers to selecting the correct materials for the application in which the engineered part is being used. This selection process includes choosing the material, paying attention to its specific type or grade based on the required properties.
