PPT-POLYMERS

AND POLYMERIZATION By Dr Rashid Hassan Assistant Professor RIHS ISLAMABAD 1 POLYMER Poly Many mer Units Ie 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. 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 performance polymers to improve the impact strength and aesthetic appearance of its polypropylene (PP) injection molded paint pails. Vistamaxx polymers also deliver better processability and cost per 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 . . 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 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. Alkenes. The commercial . process. of . hydrogenation is . used. to . convert the double . bonds. in . vegetable oils to . saturated. fats . such as those in margarine. . Learning . Goal . . Draw the condensed or line-angle structural formulas and give the names for the organic products of addition reactions of alkenes. Draw a condensed structural formula for a section of a polymer.. Biomaterials: Chemistry and Degradation. Jan 2014 – May 2014. Final Year Bachelor of Chemical Engineering. Dr. Ratnesh Jain.
