PPT-Introduction to Polymers

Overview What are polymers How are polymers named What is a polymer crosslinker Polymers are all around us Contact lenses Sport equipment Clothing polyester Plastic containers Synthetic. These polymers bring a signi64257cant contribution to the sustainable development in view of the wider range of disposal options with minor environmental impact As a result the market of these environmentally friendly materials is in rapid expansion e they possess no mobile charges and the lowest electronic excita tions are in the UV region There exists a peculiar class of polymers with quite di64256erent properties these are polymers with conjugated double bonds in the main chain They are semic 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.. Kyle Douglas, James Farber, Steven Flynn, Janie Gu, . Vivian Qin, Jenny Shih, Jake . Silberg. , Anita . Wamakima. Through Polymer Matrices. Dr. David Cincotta, Jeremy Tang. Controlled Release. Normally 1. 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. 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.. Polythiophene. for ‘Green. ’ . Organic Electronics. Tapping mode AFM (1 . m. m × 1 . m. m x 2 nm) height image showing the . nanofibrillar. morphology of a . polythiophene. -derivative conducting polymer film processed and annealed from water . 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.. . DEFINITION . A Polymer is a substance composed of molecules with a large molecular mass of repeating structural units or monomers connected by covalent chemical bonds.. . Cross . linked Polymer:. Carbohydrates, lipids, proteins, and nucleic acids. Monomers. Glucose. Amino acids. Nucleotides . Fatty acids . Polymers. Carbohydrates . Nucleic acids. Lipids . Proteins . Carbohydrates. The word carbohydrate literally means “watered carbon.”. 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. D 15.  Explain the general formation and structure of carbon-based polymers, including synthetic polymers, such as polyethylene, and biopolymers, such as carbohydrate. . Content Standard .
