Polymers are a part of our every day life and without them around‚ this world would be very‚ very different‚ if not impossible to live in. However‚ most people do not even know what a polymer is‚ or just how widespread they are around us. Polymers are formed from hydrocarbons‚ hydrocarbon derivatives‚ or sometimes from silicon. They are the basis not only for numerous natural materials‚ but also for most of the synthetic plastics that one encounters in their lives. Polymers consist of extremely large

Chemistry 26/03/2013 The polymer Introduction What is polymer? Polymer is a huge macromolecule comprise many thousands of small molecules created through Joining together chemically. Polymers are everywhere in our life. Many industries extremely rely on polymers‚ for example‚ food court‚ tons o ’toys and dollar dungeon. Those all are stuff made out of polymers. In addition there are lots kind of polymers ‚ such as aramid‚ Carbon fiber‚ Rayon and so on. Now‚ this Essay will investigate Tons

1 Experiment 15: Exploring the World of Polymers Objective: In this experiment‚ you will explore a class of chemical compounds known as polymers. You will synthesize and modify polymers‚ test their properties and use a fabrication technique to produce an object from a polymer. Introduction (See Tro‚ pp 985-987.) The importance of both natural and synthetic polymers in our lives cannot be overestimated. The desirable properties of these macromolecules‚ such as tensile strength and flexibility

6. POLYMERS and elastomers Lecture no. 1 Objectives: Definition‚ Functionality‚ Classification of high polymers – based on origin‚ molecular structure. 6.1.1. DEFINITION: The word polymer is derived from the two greek words‚ poly and meros‚ meaning many and parts or units respectively. Polymers are macro molecules formed by linking smaller molecules repeatedly‚ called monomers. Examples: Polythene is formed by linking a large number of ethene (or ethylene) molecules together
