In the first three editions of this column, the groundwork for better understanding the nature of polymers – vis-à-vis lower molecular mass materials – was laid. In this edition, we will look at factors that chemists, chemical engineers and materials scientists can, in principle, manipulate to change polymer properties. These include changes that can be made in composition, … [Read more...] about Changing Polymer Properties through Manipulation

The second edition of “Professor’s Corner” included a discussion about the fundamental physical property differences between low molecular mass materials and polymers1. These included differences in flexibility, melting point and glass transition temperature (Tg), as well as the rheological properties of liquids or solutions. In this edition, we will take a closer look at … [Read more...] about Structure and Property Relationships for Polymers
