Structure of Plastics

Plastics are materials which are created by chemical conversion of natural products or in a synthetic manner from organic compounds. The main components are the elements carbon (C) and hydrogen (H). The basis of most plastics are carbon-hydrogen compounds, from which the single components of plastics, the so-called monomers, are produced. 1) Synthesis: production of a chemical compound from different elements or simple molecules. Synthesis is the opposite of analysis. 2) Organic media are pure non-metals of natural occurrence, e. g. petroleum, coal, wood, natural gas. Inorganic media are compounds of metal and non-metals, e .g. minerals, ores etc. 3) Monomers are the basic molecules, i. e. the smallest components of which plastics are...
