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 system 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. solubility of gases in liquid polymers has been treated theoretically using the lattice-fluid model.
