Home Library Science Science of Everyday Things Concept Formed from hydrocarbons , hydrocarbon derivatives, or sometimes from silicon, polymers are the basis not only for numerous natural materials, but also for most of the synthetic plastics that one encounters every day. Polymers consist of extremely large, chain-like molecules that are, in turn, made up of numerous smaller, repeating units called monomers. Chains of polymers can be compared to paper clips linked together in long strands, and sometimes cross-linked to form even more durable chains. Polymers can be composed of more than one type of monomer , and they can be altered in other ways. Likewise they are created by two different chemical processes, and thus are divided into addition and condensation polymers. Among the natural polymers are wool, hair, silk, rubber, and sand, while the many synthetic polymers include nylon How It Works Polymersof Siliconand Carbon Polymers can be defined as large, typically chain-like molecules composed of numerous smaller, repeating units known as monomers. There are numerous varieties of monomers, and since these can be combined in different ways to form polymers, there are even more of the latter.

POLYMERS
Polymers are substances whose molecules have high molar masses and are composed of a large number of repeating units. There are both naturally occurring and synthetic polymers. Among naturally occurring polymers are proteins, starches, cellulose, and latex. Synthetic polymers are produced commercially on a very large scale and have a wide range of properties and uses. The materials commonly called plastics are all synthetic polymers. Polymers are formed by chemical reactions in which a large number of molecules called monomers are joined sequentially, forming a chain. In many polymers, only one monomer is used. In others, two or three different monomers may be combined. Polymers are classified by the characteristics of the reactions by which they are formed. If all atoms in the monomers are incorporated into the polymer, the polymer is called an addition polymer . If some of the atoms of the monomers are released into small molecules, such as water, the polymer is called a condensation polymer . Most addition polymers are made from monomers containing a double bond between carbon atoms. Such monomers are called olefins, and most commercial addition polymers are polyolefins. Condensation polymers are made from monomers that have two different groups of atoms which can join together to form, for example, ester or amide links. Polyesters are an important class of commercial polymers, as are polyamides (nylon).

Polymers
1. Introduction
Prior to the early 1920's, chemists doubted the existence of molecules having molecular weights greater than a few thousand. This limiting view was challenged by Hermann Staudinger , a German chemist with experience in studying natural compounds such as rubber and cellulose. In contrast to the prevailing rationalization of these substances as aggregates of small molecules, Staudinger proposed they were made up of macromolecules composed of 10,000 or more atoms. He formulated a polymeric structure for rubber , based on a repeating isoprene unit (referred to as a monomer). For his contributions to chemistry, Staudinger received the 1953 Nobel Prize. The terms polymer and monomer were derived from the Greek roots poly (many), mono (one) and meros (part). Recognition that polymeric macromolecules make up many important natural materials was followed by the creation of synthetic analogs having a variety of properties. Indeed, applications of these materials as fibers, flexible films, adhesives, resistant paints and tough but light solids have transformed modern society. Some important examples of these substances are discussed in the following sections.

    Lapox Epoxy Resins and Hardener systems are manufactured and marketed by Polymers division of Atul Limited. The manufacture of Epoxy systems began in 1968 in a company established as a joint venture between Atul and Ciba, Switzerland. In 1999, on the merger of the JV with the parent company, the Epoxy operations became a part of Atul Limited. Having achieved a leadership position in the domestic market of Epoxy Systems, the company intends to play its rightful part in the global market. It has plans to build on
    the success already achieved in certain segments of the European and North American markets. The strategy is to target niche markets offering customized solutions for
    challenging applications. Recently added products such as Multifunctional Epoxy Resins, Cycloaliphatic Epoxy Resins, Epoxy Novolacs, Bis F Resins, Brominated Epoxies, Reactive Diluents, Phenalkamines, and Aromatic Amines have enlarged the long-standing grades offered by the company for applications in electrical casting, composites and laminating, civil and coating industries. These are strongly supported by a well-equipped Application Development Center and synthesis as well as analytical labs. Apart from an intensive network of branch offices and dealers in India, the company has established marketing subsidiaries in the UK (Manchester), the USA (Charlotte), Germany (Weisbaden) and China (Shanghai). Besides, it has enterprising agents/dealers in the UK, France, Germany, USA and China. These dealers stock Lapox to cater to the needs of their regular customers.

Exploring Materials Engineering
Polymers
The word polymer literally means "many parts." A polymeric solid material may be considered to be one that contains many chemically bonded parts or units which themselves are bonded together to form a solid. Two industrially important polymeric materials are plastics and elastomers Plastics are a large and varied group of synthetic materials which are processed by forming or molding into shape. Just as we have many types of metals such as aluminum and copper, we have many types of plastics such as polyethylene and nylon. Plastics can be divided into two classes, thermoplastics and thermosetting plastics, depending on how they are structurally and chemically bonded. Elastomers or rubbers can be elastically deformed a large amount when a force is applied to them and can return to their original shape (or almost) when the force is released. Taken from Principles of Materials Science and Engineering , William F. Smith, McGraw-Hill , Inc., New York. We are all pretty aware of the various plastic/polymer products in our life. On the left is a montage of typical plastic extrusion products. Plastic parts are often produced by the injection molding process. To get an idea of how this is done, visit the following
