Polymer physics deals with the physical structure and also the properties of polymers, as well as the reaction kinetics of polymerisation of monomers and degradation of polymers. Polymers are giant molecules and therefore are terribly sophisticated for resolution employing a settled methodology. In the state of liquid, polymer is strongly depends on the temperature. The thermal fluctuation affects the shape of a polymer when there is an external temperature is given to a liquid state of polymer. There are many applications of polymer physics with in the space of optoelectronics, coating, medicine, food and so on. The polymers can be made in a chain form. There are two types of polymer chain.
