Effect of Zn⁺²Poly(ethylene-co-methacrylic acid) Ionomer on Mechanical Properties, Thermal Properties, Morphology and Process Rheology of Acrylonitrile Styrene Acrylate (ASA) Terpolymer

Abstract

The present study deals with acrylonitrile-styrene-acrylic elastomer (ASA) terpolymer and an ionomer based blend to develop a weather resistant material with good heat sealability and excellent adhesion properties. The mechanical properties of ASA/ionomer blends were reduced with increase in ionomer content, whereas the thermal stability was improved. On addition of ionomer, the effects of shear rate and temperature on melt viscosity were also investigated. The mechanical modulli were also carried out to justify and correlate with ionomer content. The thermal stability, investigated by thermogravimetric analysis, showed that the thermal stability was increased with the incorporation of ionomer.

Effect of o-MMT content on properties of Poly (vinyl chloride)/Poly (acrylonitrile styrene acrylate) blends

“…Thermogravimetric analysis (TGA) is an analytical technique used to characterize the decomposition and thermal stability of materials and to determine the fraction of moisture and volatile compounds present in the structure by monitoring the mass change (37). Figure 2b displayed the TGA thermograms of PVC/ASA/o-MMT nanocomposite films which were shifted to higher temperatures with the addition of o-MMT nanoparticles and their increased amounts in the PVC/ASA blend matrix.…”

Characterization of Europium Complex-doped PMMA and PMMA-EVA Polymer Networks

“…The examination of the emission or absorption characteristics of complex doped polymeric systems has by now, grown to an exciting area of research [1][2][3][4] . Rare earth complex doped polymers are important because they combine the impressive optical features of the complexes and the advantageous mechanical properties of polymeric matrix; both important factors in the fabrication of stable optoelectronic materials.…”

Dynamic ionic behavior of gel-free diolefin rubber-based carboxylate ionomers preparedviaolefin metathesis

“…18,19 Meanwhile, under the alternating stress, the reversible ionic bonds can be repeatedly broken and reorganized to dissipate a large amount of energy, which is beneficial for enhancing the intermolecular interactions and limiting the mutual slippage between chains, thereby enhancing the mechanical strength and damping performance. 20–22 Therefore, the incorporation of acid groups in a rubber matrix and the control over the acid group content are of crucial importance for the preparation of rubber-based ionomers.…”
