Polymers are materials made of long, repeating chains of molecules. The materials have unique properties, depending on the type of molecules being bonded and how they are bonded. Some polymers bend and stretch, like rubber and polyester.The eight most common types of synthetic organic polymers, which are commonly found in households are Low-density polyethylene (LDPE), High-density polyethylene (HDPE), Polypropylene (PP), Polyvinyl chloride (PVC), Polystyrene (PS), Nylon, nylon 6, nylon 6,6.,Teflon (Polytetrafluoroethylene), Thermoplastic polyurethanes (TPU). Due to the importance of the field in our daily lives, the requirement for Polymer Engineers is rising at a very fast pace. Polymer Engineers with enhanced knowledge is finding good positions in the industries viz. Petroleum Industry, Oil Industry, Polymer Industry, Rubber Industry etc.

Polymer Technology or Macromolecular Science is the subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics. The field of polymer science includes researchers in multiple disciplines including chemistry, physics, and engineering. Polymers are materials made of long, repeating chains of molecules.
