SSH redirects here. For other uses, see SSH (disambiguation). Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. The best known example application is for remote login to computer systems by users.
Poly means many and mer means parts.. So polymer means many parts.. The parts are usually the same part used repeatedly in a chain-like manner. Polymers are also referred to as plastics because they are easily molded.ature has many examples of polymers. Cotton fibers are made of sugar molecules that are repeated in a chain-like manner. Hair, wool, and other natural fibers are polymers. They are made by chaining one or two substances one after another.
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.he materials commonly called plastics are all synthetic polymers.
