Dynamic Mechanical and Spectroscopic Study of Ionomer Blends Based on Carboxylated or Sulfonated Flexible Polystyrene and Rigid Poly(diacetylenes) with Functional Side Groups

The dynamic mechanical and infrared spectroscopic investigation of ionomer blends of poly-(diacety1ene)-a nd polystyrene-based ionomers has shown that miscibility of this usually incompatible polymerpair can be achieved through ion-ion interactions between the blend components. Microphase separationis prevented through ionic contacts generated during the blend formation; a schematic model of mixing inthe blends is proposed
