Viscoelastic properties of poly(styrene-co-acrylate) and poly(vinylcyclohexane-co-acrylate) ionomers

Clustering in carboxylated polysulfone ionomers: A characterization by dynamic mechanical and small-angle X-ray scattering methods

“…11,12 It was also found that the volume fraction of clusters in the carboxylated ionomer is higher than that in the sulfonates at the same ion content. 11 This difference is related to the relative sizes of multiplets in these two systems. 11,12 Polysulfone is a high-performance thermoplastic resin with good toughness, high temperature resistance, and high impact strength.…”

“…[3][4][5][6][7][8][9][10] For example, the cluster T g of sodium polystyrenesulfonate is about 120°C higher than the matrix T g , whereas the cluster T g of the sodium polystyrene-co-methacrylate is about 70°C higher than the matrix T g . 11 This difference is due to the difference in the strength of the ionic interactions. 11,12 It was also found that the volume fraction of clusters in the carboxylated ionomer is higher than that in the sulfonates at the same ion content.…”

Fluorimetry and differential scanning calorimetry analysis of ionomers with low Eu3+ contents

“…4 It has also been cades, this powerful research tool has also been shown that when the ion content is higher than applied in the study of the structure of synthetic a critical value, another phase, namely clusters, polymers. 11 When two polymers are labeled with may be formed in ionomers and be detected by donor and acceptor chromophors, respectively, differential scanning calorimeter (DSC), 5 dyand a film is cast from a solution containing a mixture of the two, nonradiative energy transfer from the donor to the acceptor occurs; this will be phases, but may be extensive if they form a single ent Eu 3/ contents were obtained. MMA was prepolymerized in bulk with AIBN as initiator (0.2 phase.…”
