Document Summary
Polymers are nding increasing use throughout our society. Well over 100 bil- lion pounds of polymer are produced each year, and it is expected that this gure will double in the coming years as higher-strength plastics and composite mate- rials replace metals in automobiles and other products. Consequently, the eld of polymerization reaction engineering will have an even more prominent place in the chemical engineering profession. ), it is the intention here to give only the most rudimentary thumbnail sketch of some of the principles of polymerization. A polymer is a molecule made up of repeating structural (monomer) units. For example, polyethylene is used for such things as tubing, and repeat- ing units of ethylene are used to make electrical insulation: nch2 ch2 ch. 2 n where may be 25,000 or higher. n. Polymerization is the process in which monomer units are linked by chem- ical reaction to form long chains.
