Polymer Chemistry Classification of Polymers – Notes prepared by The most common way of classifying polymers is to separate them into three groups - thermoplastics‚ thermosets‚ and elastomers5. The thermoplastics can be divided into two types - those that are crystalline and those that are amorphous. You may click on the words in the diagram below to learn more about these classifications. Thermoplastics Molecules in a thermoplastic are held together by relatively weak intermolecular

The gifts of chemistry are a boon to mankind. Its applications in home and industry are many. Right from purified drinking water and motor car to cane sugar and mobile phone‚ all these have been made possible only through processes in chemistry at some stage or other of production. New discoveries‚ processes‚ and products are an integral part of this fascinating discipline. It offers a fertile ground for those endowed with intellectual curiosity and a passion for scientific research. you must

The importance of food chemistry lies in its ability to counter the effects of decomposition and spoilage and extend the shelf life of foods. Food chemistry is a science that studies the chemical processes that take place in food. All food products are made of biological materials that react and interact in different ways‚ and under different

Nuclear Chemistry Imagine the majority of Earth being quarantined off and people having to live in specified areas to avoid harmful radiation that originated from nuclear energy/waste. The integration of nuclear energy/medicine is largely controversial among people. Every side to the argument has its benefits as well as its negative consequences. Nuclear energy should not be used in society because of the threat it poses to thousands of people. In contrast‚ nuclear medicine has positive aspects that

Sustainable Chemistry Terry Collins* Chemistry has an important role to play in achieving a sustainable civilization on Earth. The present economy remains utterly dependent on a massive inward flow of natural resources that includes vast amounts of nonrenewables. This is followed by a reverse flow of economically spent matter back to the ecosphere. Chemical sustainability problems are determined largely by these economy-ecosphere materials flows (see the figure‚ below)‚ which current chemistry education
