The purpose of this web page is to provide a practical resource for understanding modeling techniques that can be use to characterize the processing-structure-property relationship of semi-crystalline polymers. The site will begin by outlining some general subjects in polymer science, then progress into some specific examples of models of polymer processes.
This web page was written in 2005 by Ryan Breese as a supplement to the work that Dr. Greg Beaucage of the University of Cincinnati (the author's graduate research advisor) had completed in creating a virtual polymer classroom on the internet. The following link will direct you to Dr. Beaucage's home page, which includes details regarding his research and links to numerous sites containing information on several fields of interest in polymer science.
Goal of this web page:
This particular web page will combine general mathematics, fundamental concepts of polymer science, and practical examples to show how modeling can explain the processing-structure-property relationships of semi-crystalline polymers. Such models are of interest, both in academia and industry, for understanding the behavior of polymers when exposed to various processing conditions. This understanding is then later used to predict the physical properties of a finished product, such as a blown film or injection molded parts. The ability to model a process is a powerful capability that will provide a deeper understanding of a process that enables the researcher to efficiently troubleshoot and optimize a process, as well as develop new products.
Several fundamental concepts regarding semi-crystalline polymers will serve as the foundation for the various modeling examples. These topics include:
 |
Mathematics - Quiz - Solutions |
