Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. INTRODUCTION OF POLYMER The world polymer is derived from the Greek words : poly + meros poly = many Meros = parts Polymer is the combination of large no. Natural rubber is a polymer whose repeating unit is isoprene. Fibers include many types of synthetic yarn or rope that are made from amorphous materials such as the polyesters. Polyhydroxyalkanoates or PHAs are polyesters produced in nature by numerous microorganisms, including through bacterial fermentation of sugars or lipids. Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). APPLICATION OF POLYMER 2. These issues will be discussed at length in the next chapter. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications. When produced by bacteria they serve as both a source of energy and as a carbon store. Elastomers Rubber is the most important of all elastomers. Synthesis. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Tacticity (from Greek τακτικός taktikos "of or relating to arrangement or order") is the relative stereochemistry of adjacent chiral centers within a macromolecule. These are by no means all of the applications, but a cross section of the ways polymers are used in industry. Antimicrobial polymers, also known as polymeric biocides, is a class of polymers with antimicrobial activity, or the ability to inhibit the growth of microorganisms such as bacteria, fungi or protozoans.These polymers have been engineered to mimic antimicrobial peptides which are used by the immune systems of living things to kill bacteria. of repeating units of monomers. The most widely used method for linear polymers is based on a two-step process. 2, No. Another application of polymers is the long strands known as fibers. All kinds of polymers, either conventional engineering polymer or newly developed one, … We are going to discuss some of the main polymers used in our lives. More than 150 different monomers can be combined within this family to give materials with extremely different properties. APPLICATIONS OF POLYMERS:-Molecular science has developed enormously in recent eras. Conducting Polymers and t heir Applications Current Physical Chemistry, 2012, Vol. Molecular science has a major role in our lives. This section of Polymer Applications under Polymers is a right channel to publish all types of applications related to polymeric materials and their composites. Many of the useful properties of polymers are in fact unique to polymers and are due to their long chain molecular structure. The method of synthesis depends on the type of polyphosphazene. This section presents some common applications of the polymer classes introduced in the section on Polymer Structure. It has become a necessity in our daily routines we shall talk now about the basic applications of polymers without which life wasn’t that easy.
