PPT-Polymers and their Properties

C2 Chapter 2 Learning Objectives To be able to list and state uses of commonly used polymers To be able to recall and describe the conditions required for the production of LDPE HDPE thermosetting and thermosoftening polymers. By. HEAD OF DEPARTMENT. Dr. Rashid Hassan. Assistant professor. R.I.H.S. ISLAMABAD. 1. DENTURE BASE MATERIALS. Denture base materials can be divided into two types.. 1. METALLIC DENTURE BASE:. Gold alloys, cobalt chromium alloys.. Polymers. . C.X.C objectives. Students should be able to :. Define polymers. Distinguish between addition and condensation as reactions in the formation of polymers. Name examples of polymers formed by:. C1.5. What do I need to know?. Recall. how hydrocarbons can be cracked to make smaller more useful molecules.. Describe. some of the properties of alkenes. Explain. how alkenes can be used to synthesise polymers for a wide range of different applications.. What is petroleum?. Also known as crude oil. It is a thick black sludge. It comes from ancient plant and animal life long since buried and kept under extreme pressure for millions of years.. It is composed of countless different organic compounds.. Condensation Polymers. Involves 2 monomers that have different functional groups.. They also involve the elimination of water or another small molecule. . Hence the term . condensation. polymer. . Monomer A + Monomer B . AND . POLYMERIZATION. By. Dr Rashid Hassan. Assistant Professor. RIHS. ISLAMABAD. 1. POLYMER. Poly = Many mer = Units. I.e. a material made up of many units.. Properly defined as:. Chemical compound composed of large organic molecules formed by the union of many repeating small monomer units.. . Polymers. are large molecules made up of repeating units called . Monomers. The synthetic process is. Polymerization.. E.g. . Note – define repeating unit in terms of monomer structure. Degree of Polymerization. Polymers. are long molecules made of repeating units, called . monomers. .. In general. :. Specific example. :. Forces between polymer chains: Crosslinks. Weak: Intermolecular . force crosslinks. Strong: Colvalent. Biomaterials: Chemistry and Degradation. Jan 2014 – May 2014. Final Year Bachelor of Chemical Engineering. Dr. Ratnesh Jain. UGC Assistant Professor. Page . 2. . 1) B. . Ratner. , A. Hoffman, F. Schoen, and J. Lemons: . As this is a new skill, in year 10 we will work through some challenges together, so you can see how it is done.. As we will be working on this as a class, many of the outcomes will be similar. In the real NEA, everyone’s project will be completely different.. Let’s review: . What are the 4 macromolecules of life?. Let’s Review . 2. What are the monomers of each macromolecule?. 3. What are the polymers of of each macromolecules. 4. Predict: How do you think we go from monomer to polymer?. Noah Brubaker. June 29. th. , 2011. Hydrocarbons. ex: Alkanes. 1 – Meth-. 2 – Eth-. 3 – Prop-. 4 – But-. 5 . – . Pent-. 6 – Hex-. 7 – .

Polymers . may be naturally found in plants and animals (natural polymers) or may be man-made (synthetic polymers).. → . the . synthesis of new polymers by modification of existing . polymers using . a variety of chemical . reactions. 1) . the esterification of cellulose, crosslinking of . polyisoprene. , hydrolysis.
