Follow the link above to start or download this activity.

This Activity Requires:

  • Java 1.5+ - Java 1.5+ is available for Windows, Linux, and Mac OS X 10.4 and greater. If you are using Mac OS X 10.3, you can download MW Version 1.3 and explore within it instead.

      Test your system to see if it meets the requirements

Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

There are two types of polymerization, chain growth polymerization and step growth polymerization. In the first type, chain growth, only monomers can react with growing chains. Growing chains do not combine with each other into bigger chains. In the second kind of polymerization, the growing chains may react with each other to form longer chains. This simulation demonstrates the second kind of polymerization.
