Session: Crystallization of Rubber-PM (191st Spring Technical Meeting)

Crystallization of Rubber-PM

Crystallization is not only a fundamental aspect of the physics of polymers, but also plays a significant role in the mechanical and failure properties of many elastomers. The purpose of this session is to present recent developments in understanding what governs crystallization and how crystallinity affects performance.
