Characteristics of rubber polymer.

As nouns the difference between polymer and rubber is that polymer is organic chemistry a long or larger molecule consisting of a chain or network of many repeating units formed by chemically bonding together many identical or similar small molecules called monomers a polymer is formed by polymerization the joining of many monomer molecules while rubber is. Natural rubber is an addition polymer that is obtained as a milky white fluid known as latex from a tropical rubber tree. Natural rubber is still an important industrial polymer but it now competes with a number of synthetics such as styrene butadiene rubber and butadiene rubber which are derived from by products of petroleum and natural gas. Types of polyisoprene that are used as natural rubbers are classified as elastomers.

Due to their broad spectrum of properties both synthetic and natural polymers play essential and ubiquitous roles in everyday life. In natural rubber most of the double fonds formed in the polymer chain have the z configuration resulting in natural rubber s elastomer qualities. The elastic properties arise from the its ability to stretch the chains apart but when the tension is released the chains snap back to the original position. Natural polymers include such materials as silk shellac bitumen rubber and cellulose.

Natural rubber also called india rubber latex amazonian rubber caucho or caoutchouc as initially produced consists of polymers of the organic compound isoprene with minor impurities of other organic compounds plus water thailand and indonesia are two of the leading rubber producers. However the majority of polymers or plastics used for engineering design are synthetic and often they are specifically formulated or designed by chemists or chemical engineers to serve a specific purpose. Charles goodyear accidentally discovered that by mixing sulfur and rubber the properties of the rubber improved in being tougher resistant to heat and cold and increased in elasticity. Polymers range from familiar synthetic plastics such as polystyrene to.

This article reviews the composition structure and properties of both natural and synthetic elastomers. Greek poly many mer part is a substance or material consisting of very large molecules or macromolecules composed of many repeating subunits.
