Introduction To Synthetic Polymers
The word polymer is derived from the classical Greek words poly meaning “many” and meres meaning “parts.” Simply stated, a polymer is a long-chain molecule that is composed of a large number of repeating units of identical structure.... The synthetic methods used to prepare this and other polymers will be described later in this chapter. Unlike simpler pure compounds, most polymers are not composed of identical molecules. The HDPE molecules, for example, are all long carbon chains, but the …

Synthetic Polymers Polymers Biodegradation Scribd

Polymers have many inherent properties that can be further enhanced by a wide range of additives to broaden their uses and applications. Polymers can be made to mimic cotton, silk, and wool fibers; porcelain and marble; and aluminum and zinc. Polymers can also make possible products that do not readily come from the natural world, such as clear sheets and flexible films....
time around the world, which is used for daily use like packaging materials, carry bags, manufacturing of different types of materials etc. So, to replace the use of synthetic plastic as well as to reduce the

List of some common man-made Polymers and their Uses
Synthetic resins, in which plastics are also included, vary widely in their chemical composition and in their physical properties. The number of synthetic resins which can be made is vast; relatively few, however, have achieved commercial importance. Some of the polymers that have achieved commercial importance and their uses are tabulated in Table 1 and some of their important physical cia world factbook 2014 pdf As such, in this article, we will list some of the important polymers and their uses in the industries and other fields. Types of Polymers Polypropene, also known as …. Drawing for the absolute and utter beginner pdf

Most common polymer. Used in bags, wire insulation, and squeeze bottles Polypropylene CH2=CH The First Synthetic Polymer Bakelite, a phenol-formaldehyde polymer, was the first completely synthetic plastic, first made by Leo Baekeland in 1907. Baekeland and an assistant started their research in 1904 looking for a synthetic substitute for shellac. Bakelite was commercially introduced …

  • The preparation of uniform polymers and their use in fundamental polymer chemistry are reviewed. A typical method of preparation is a combination of living polymerization and supercritical fluid
  • According to their origin, polymers are divided into two basic groups, viz., natural polymers and synthetic polymers. The most important classes of natural polymers are polysaccharides - basic structural materials of plants, proteins - fundamental structural . UNESCO – EOLSS SAMPLE CHAPTERS MATERIALS SCIENCE AND ENGINEERING – Vol. I – Structure and Properties of Polymers …
