PPT-Polymers

Polymers CXC 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. 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 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. 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..
