A polymer is a huge particle, or macromolecule, made out of many rehashed subunits. Due to their wide scope of properties,both engineered and common polymers assume basic and universal jobs in regular life. Polymers run from recognizable manufactured plastics, for example, polystyrene to normal biopolymers, for example, DNA and proteins that are key to natural structure and capacity. Polymers, both common and manufactured, are made through polymerization of numerous little particles, known as monomers. Their therefore enormous atomic mass, comparative with little particle mixes, produces interesting physical properties including strength, viscoelasticity, and an inclination to shape glasses and semicrystalline structures instead of gems. The terms polymer and gum are regularly equivalent with plastic.
