    Polymers Introduction: Polymers are substances that are composed of subunits. The recurring subunits in polymers are termed as monomers. These monomer subunits are mostly large hence making polymer a macromolecule. Due to their diverse applications polymers are considered to be used a lot in our everyday life for example in adhesives or in rubber. The importance of polymers in nature can be found by their role in biology as DNA which is a macromolecule with repeating subunits. The process of polymers

    The word polymer is defined as, "a compound of high molecular weight derived either by the addition of many smaller molecules, as polyethylene, or by the condensation of many smaller molecules with the elimination of water, alcohol, or the like, as nylon" ("Reference"). In laymen terms, a polymer is a chain of monomers. The prefix poly- means "many", and mono- means "one" ("What is a polymer"). Monomers string together to form linear chains through a process called polymerization. Polymerization

  • PVC: The Different Types Of Polymers

    872 Words  | 4 Pages

    A polymer by definition is a structure composed by joining small repeating molecules called monomers to form large chains. This class of matter is subdivided into many types based on the way these monomers are attached to the chains or on the way these chains reside with one another. One such is thermoplastic polymers which are linked by intermolecular interactions to form branched or linear chains. Polymers of this category are easily melted and shaped numerous times as they do not go significant

    Polymer is large molecule formed from the merger of many small molecules known as monomer. The word polymer is derived from the Greek word Poly, which means “many” and Mer, which means “parts”. There are 2 types of polymer: natural polymer and synthetic polymer. The history of natural polymer goes back as long as man has been using wood, which composed of cellulose. Natural polymers exist in nature and can be extracted. Examples of natural polymers are cellulose, starch, glycogen, protein and nucleic
