Polymers

Polymer, any of a category of natural or synthetic substances composed of very massive molecules, called macromolecules. Polymers make up among the substances in living organisms, which includes, as an example, proteins, cellulose, and nucleic acids. Furthermore, they represent the basis of some minerals like diamond, quartz, and feldspar and man-made materials like concrete, glass, paper, plastics, and rubbers. Polymers have residences that rely upon the chemical compounds from which they are made from, and the situations in which they are made. As an example, there are two principal forms of polythene: LDPE, low-density polythene and HDPE, high-density polythene, and will become softer at decrease temperatures. Types of polymers and there uses-

• Polythene – plastic bags and bottles
• Polypropene – crates and ropes
•  Polychloroethene – water pipes and insulation on electricity cables
