Fracture Behavior of Ionomers and Ionomeric Blends

Abstract

We have elucidated the deformation/fracture behavior of ionomers, and correlated them to their microstructure. We have also found important molecular variables to achieve enhanced fracture properties of ionomers: high ion content above a critical value, divalent counterions, and excess neutralizing agent. We have elucidated the structural changes associated with the change of each molecular variable. Subsequently, we have produced unique blends made of small amounts of ionomers and large amounts of unmodified polymers. They show synergistic mechanical behavior, retention of transparency of the unmodified polymer, good processability, and excellent cost performance. We have elucidated the structural characteristics responsible for these behavior. (Author)
