Polymers can be made to mimic cotton, silk, and wool fibers; porcelain and marble; and aluminum and zinc. Crystalline polymers Areas in polymer where chains packed in regular way. Polymers are classified as: (1) Man-made or synthetic polymers that are synthesized in the laboratory; (2) Biological polymer that are found in nature. PowerPoint Presentation : Cross linked or Network polymers These are usually formed from bi-functional and tri-functional monomers and contain strong covalent bonds between various linear polymer chains, e.g. molecule and hydrogen atoms are bonded along the.

X-ray scattering Can determine precise crystal structure. These two factors can help in understanding the varied properties of polymers and also the reason why polymers are very different from materials like metals and ceramics. Polymer contains both crystalline and amorphous phase within arranged randomly. One of the great design strengths of composites is the multiple The word polymer is derived from the classical Greek words poly meaning “many” and meres meaning “parts.” Simply stated, a polymer is a long-chain molecule that is composed of a large number of repeating units of identical structure. Mechanical and chemical properties of polymer materials are of great importance to know before use in any construction applications. Lesson slides to teach AQA properties of polymers AQA 2.2.5.
