1. IntroductionPolymeric materials play a functional role in every aspect of daily life, from clothing to infrastructure. Polymers differ greatly from other materials, such as ceramics or metals, based on the type of bond. Metals bond metallically, creating a sea of ​​electrons, and ceramics generally bond ionically, strongly binding electrons to lattice points. Polymers bond covalently in carbon chains, which (in general) makes their properties more variable due to arrangement possibilities in bond length, angle, and molecular configuration. Polymers, on average, tend to be lighter, have a wider range of colors, lower thermal and electrical conductivity, lower brittleness, greater resistance to acids, bases, and moisture, and higher dielectric strength than polymers. their ceramic or metallic counterparts, but with wide range. This variety of properties leads to different classifications and therefore different processing methods based on the classification of the polymer.2. Polymer Classifications Polymer processing differs greatly based on the category of polymer within the system. Polymers can be classified based on their chemical composition, structure or behavior in tests (thermal or mechanical).2.1. By chemical composition Most polymers are organic molecules, based on a repeating carbon skeleton, but they can also include other elements within the chain, most often oxygen, nitrogen or sulfur. The basic unit of a polymer chain is known as a monomer or mer. The composition of the monomer will greatly influence the properties shown. Monomers can be natural or created synthetically. Examples of common monomers can be seen in Figures 1-4. Within the monomer, the electronegativity and bonding properties of the constituent and...... middle of paper......, Expert Services.
