PPT-Polymers

What is a polymer Important polymers Plastics Rubbers Proteins Starch Cellulose Lignin Fats PAHs Polymers from alkenes Addition reactions Polymerisation Other important monomers. Many people think of polymers simply as plastics used for packaging in household objects and for making fibres but this is just the tip of the iceberg Polymers are used in all sorts of applications you might not have thought much about before for ex 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:. 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.. 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.. Formulation and Evaluation of Isoniazid Mucoadhesive, nanospheres embedded micro particulates inhalable dry power. Gnanaprakash. . Ph.D. Associate Professor. Department of Pharmaceutics. P. Rami Reddy Memorial College of Pharmacy, India. . 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. . 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:. . 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. 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. 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: . 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 . What is a monomer and what is a polymer?. Phenomenon:. . experiment by pouring the gel. Have you ever seen anything that acts like this gel?. What is happening to the molecules to make it act this way?. Show the beads in the jar and how they will keep falling out after you start them..
