“…Recently, we have made polymeric materials more fracture resistant and tougher by creating rigid -rigid polymer blends that contain ionic interactions [9,10]. The rigid -rigid blends are made of an ionomer and an ionomer precursor polymer, such as those made of sulfonated polystyrene (SPS) ionomer and PS, or those made of poly(methyl methacrylate)(PMMA)-based ionomer and PMMA.…”

“…It is well known that entanglements are a prerequisite for strength in polymeric systems, and also for good interfacial adhesion [11,12]. Synergistic enhancement in both tensile strength and fracture energy has been achieved in these blends [9,10].…”

“…Young's modulus data presented in Figure 1(b) reveals highly non‐ideal behavior, with PE‐ g ‐PA/HDPE blends exhibiting much greater stiffness than either of the constituent materials. Similar synergistic effects have been documented for immiscible blends polystyrene/sulfonated polystyrene ionomers7 and poly(methyl methacrylate)/and partially neutralized poly[(methyl methacrylate)‐ co ‐(methacrylic acid)] ionomers 9. Unfortunately, the structural similarity of HDPE and the backbone of PE‐ g ‐PA preclude the use of standard calorimetric and imaging techniques for assessing blend morphology, and we must base our evaluations solely on the rheological and physical property evidence presented.…”

Rheological and solid‐state physical properties of blends containing high‐density polyethylene (HDPE) and a polyampholyte derivative (PE‐g‐PA) are assessed along with their onium ion‐exchanged montmorillonite clay (NR 4+‐MM) nanocomposites. Strong deviations from the log‐additivity rule of zero‐shear viscosity, combined with synergistic behavior in tensile moduli, are consistent with a multi‐phase blend morphology. While this affects clay dispersion in filled blends, PE‐g‐PA/HDPE based nanocomposites are shown to exhibit a favorable balance between material stiffness and ductility.

“…However, the glass transition temperature ( T g ) of PMMA is relatively low and this is considered as a drawback in the above‐mentioned applications. Several approaches have been suggested by many authors to raise the T g value of this polymer 4–9. Such approaches are based mainly on two routes: either to blend PMMA with other high‐temperature polymers (possessing higher T g values)4–6 or through copolymerization of MMA with other monomers 7–9.…”

Terpolymer samples were prepared by free radical polymerization of methyl methacrylate (MMA), indene (In) and acrylonitrile (AN) in bulk. The samples were chosen so that the molar ratio of AN to MMA varied from 1.00:4.39 to 1.00:0.83, while the molar ratio of In was kept almost unchanged. The glass transition temperatures (T g ) of the samples were determined using differential scanning calorimetry. Moreover, isochronal dynamic mechanical measurements of the complex bending modulus as well as the complex dielectric permittivity were carried out over wide temperature ranges, namely from 50 to 190• C, depending on the material investigated. All samples exhibited a single common T g value, which increased to higher temperature upon increasing the content of AN. In addition, the results were investigated quantitatively in the framework of a molecular model.
