Solid-state NMR Analysis of Blends of Nylon 6 and Zinc Salts of Sulfonated Polystyrene Ionomers
Solid-state NMR was used to establish the specific intermolecular interactions responsible for the miscibility of blends of nylon 6 (PA6) and the zinc salt of lightly sulfonated polystyrene (Zn-SPS) and to characterize the scale of molecular mixing. l 3 C CPIMAS spectroscopy identified the interpolymer interaction as a complex between the Zn2+ cation of the ionomer and the amide nitrogen. Measu...
متن کاملProtonation of polyaniline with lightly sulfonated polystyrene
Protonation of polyaniline base with lightly sulfonated polystyrene in polar solvents such its dimethyl sulfoxide and N-methyl-2-py~olidone was investigated by UV-Vis absorption spectra. As the molar ratio of sulfonated polystyrenelpolyaniline increases, the conversion from polyaniline base form to salt form is observed owing 10 incrensed protonation. The isosbestic point clearly shows that qui...
متن کاملNMR Analysis of Sulfonated Polystyrene
Atactic polystyrene (PS) has an amorphous structure. Compounds such as H2SO4 and SO3 are commonly used as sulfonating agents for various polymers, including PS. The main purpose of this work is to study chemical structural changes in PS arising from sulfonation through DSC analysis and NMR spectroscopy. An increase in the glass transition temperature (Tg) of sulfonated polystyrene and a decreas...
متن کاملCompatibility and mechanical properties of blends of polystyrene with biodegradable polyesters
Biodegradable polyesters allow the development of acceptable bio-composites and bio-blends from agricultural-based raw materials without impairing their biodegradability and other useful properties. The tensile properties of binary blends of polystyrene (PS) with the biodegradable polyesters polycaprolactone (PCL), D,L-polylactic acid (PLA), and Eastar Bio Ultra (EBU) were investigated. Blend c...
متن کاملAssessment of time-temperature superposition of linear viscoelastic behaviour of strongly interacting polymer blends: N-methylated nylon-2,lO and lightly sulfonated polystyrene ionomers
The applicability of time-temperature superposition of dynamic mechanical data for miscible polymer blends that exhibit strong intermolecular interactions was investigated. Blends of the lithium salt of lightly sulfonated polystyrene ionomers (Li-SPS), 9-12mol% sulfonation, and N-methylated nylon-2,lO (mPA) were miscible over the composition range studied, 30-70 wt% ionomer. Time-temperature su...
