A polymer is a substance or material comprising of enormous particles, or macromolecules, made out of many rehashing subunits. Due to their wide range of properties, both manufactured and characteristic polymers assume basic and pervasive jobs in regular life. Polymers go from recognizable engineered plastics. Polymers, both regular and manufactured, are made by means of polymerization of numerous little particles, known as monomers. Their therefore huge sub-atomic mass, comparative with little particle mixes, produces one of a kind physical properties including sturdiness, high flexibility, viscoelasticity, and a propensity to frame undefined and semicrystalline structures instead of precious stones. The expression "polymer" gets from the Greek word and alludes to enormous atoms whose structure is made out of numerous rehashing units, from which starts a trait of high relative sub-atomic mass and chaperon properties.
