Polymer-Polymer Interactions

Abstract

Our approach for understanding polymer-polymer interactions is to measure heats of mixing of small molecule analogs. In particular, we have focused on small molecule analogs of polystyrene (PS) and poly (2,6 dimethyl phenylene oxide) (PPO). This well-known systems is miscible, but the origin of its miscibility has perplexed investigators for over 25 years. Our measurements and associated molecular mechanics/Monte Carlo calculations have firmly established that the two methyl groups on PPO play a significant role in affecting miscibility. We have developed two equation of state models for hydrogen bonding interactions. They represent a significant advance in our understanding of hydrogen bonding interactions in both polymeric and non- polymeric systems. The models have been successfully applied to a variety of systems that include supercritical fluids
