Polymers are long chains of monomeric compounds that are produced by polymerisation of these monomers. Ranging from natural to synthetic, polymers play a very ubiquitous role in pharmaceutical sciences and chemistry. Polystyrene, nylon is some of the examples of synthetic polymers whereas DNA and proteins are called as biopolymers. A most common example of polymer is polythene bag. Natural compound materials like shellac, amber, wool, silk and natural rubber are used for hundreds of years. A spread of alternative natural polymers exists, like polysaccharide, that is that the main constituent of wood and paper. The list of artificial polymers includes India rubber, phenol aldehyde rosin (or Bakelite), neoprene, nylon, polyvinyl resin (PVC or vinyl), vinylbenzene, polythene, plastic, polyacrylonitrile, PVB, silicone, and plenty of additional. Most ordinarily, the ceaselessly coupled backbone of a chemical compound used for the preparation of plastics consists chiefly of carbon atoms.
A journal is a periodical publication intended to further progress of science, usually by reporting new research. Most journals are highly specialized, although some of the oldest journals publish articles, reviews, editorials, short communications, letters, and scientific papers across a wide range of scientific fields. Journals contain articles that peer reviewed, in an attempt to ensure that articles meet the journal's standards of quality, and scientific validity. Each such journal article becomes part of the permanent scientific record.
