Polymer is a term used to describe large molecules consisting of repeating structural units (monomers) connected by covalent chemical bonds. The substance is a liquid organic substance, obtained from a chemical reaction. As an example of cross-linking, sulfhydryl (-S-H) groups in two cysteine amino acid units in polypeptide chains can bond together to make a disulfide bridge (-S-S-) joining the chains together. Natural polymers include rubber, silk and cellulose (found in plants and used to make paper, for example). What is a Polymer – Definition, Classification, General Properties 2. The substances used as starting materials react in such a way that one or more units are linked together (covalently bound). The structure of a polymeric material can be described at different length scales, from the sub-nm length scale up to the macroscopic one. atoms are used. The process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer, is named Polymerization. Solution for Identify the repeating unit in the polymer formed from the following reaction sequence. Linear, branched, and cross-linked. polymer A substance made from long chains of repeating groups of atoms.

Polymers make up many of the materials in living organisms, and they constitute the basis of certain minerals and human-made materials, such as paper and plastics. Each unit cell is composed of one or more molecular units. A single polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. is used when drawing a displayed formula. a dimer, a trimer, and a polymer? A polymer consists of a backbone, made up of repeating units. The main difference between polymer and macromolecule is that polymers contain repeating units that represent the monomers whereas not all macromolecules have a monomer in their structure.
