Research Paper on Polymer Chemistry

Example Research Paper on Polymer Chemistry:
Introduction
Polymerization refers to a chemical reaction that results in bonding of two monomers to form a polymer (Tarle, 435). A polymer molecule is made up of hundreds, thousands, or even millions of atoms joined together to form a chain with an extended length at least an order of magnitude greater than its thickness (Peacock & Calhoun, 2006). Polymers have variations of molecular weight (length), branching, steric configuration, interconnections and chemical defects (Tarle, 435).

A polymer is made up of many elements. One can consider a polymer as a thread with every link of this string forming a fundamental unit which is in turn made of hydrogen, carbon, silicon and oxygen(Tarle, 435). They are mostly made up of hydrocarbons though other elements such as Sulphur, nitrogen and chlorine may also be found(Carraher & Charles, 2). The molecules are held together by covalent bonds that are branched, linear, or networked to form the polymeric material (Carraher & Charles, 2). While most polymers have carbon as their backbone, others have silicon as the main element holding the polymer (Carraher & Charles, 2). .

The history of polymerization
The science of polymerisation began way back in the 19th century where alumina-silica glass and phosphoric acid was widely applied to fill dentures (Carraher & Charles, 2). . However, the compounds had very poor mechanical properties and high solubility. This meant that they were not particularly suited in sensitive applications such as dentistry. Later in the mid 20th century, acrylic resins replaced the silica compounds as the only synthetic material (Carraher & Charles, 2). …
