“…As reported previously, CPPO/PS (50/50) blends 5 are no longer miscible when the carboxylation degree is above 9.0 mol %. This is due to the carboxThermal Analysis ylic groups' aggregation which hinders the thorough mixing of the remaining PPO and PS.…”

“…These effects have been cibility of PPO/PS blends has been extended to attributed mainly to the aggregation of the ionic miscibility studies of blends containing a compogroups into physical crosslinking sites due to ionnent modified with polar groups, such as PPO/ pair interaction. It was therefore difficult to halogenated PS, 2 PPO/sulfonated PS or carboxylachieve miscibility when the ionic groups in one ated PS, 3 brominated PPO/PS, 4 carboxylated of components tended to aggregate into a nanome-PPO/PS, 5 and sulfonated PPO/PS 6 blends.

ABSTRACT:The phase behavior of a series of blends obtained from mixing carboxylated poly(phenylene oxide) with sulfonated polystyrene and their respective neutralized ionomers was studied by differential scanning calorimetry. A substantially broader range of miscibility was observed when both blend components were functionalized, compared with blends in which only one of the components contained an acid group or was an ionomer. The properties of metallic cations which were used to neutralize the acid groups in the blends were found to have an effect on the miscibility. The miscibility of the two acid polymers or their ionomers depended on the difference of their functionalization level instead of on the absolute percentage of functional groups on each polymer. It was found that the two acid polymers or their ionomers remained miscible as long as they had a similar percentage of functional groups.

In this study, a calcium-containing monomer, namely calcium lactate, was used for the synthesis of calcium-containing polyurethane for use in biomedical applications. Ether-based polyurethane was prepared using poly(oxytetramethylene)glycol, hexamethylene diisocyanate and calcium lactate. The prepared polymer was characterized by FTIR spectroscopy, which confirmed the presence of ionic linkages in the main chain. The thermal behavior, mechanical properties and viscosity of the polymer were studied, and the properties were compared with those of a control polyurethane sample without any metal. Because of ionic clustering in calcium lactate-incorporated ionic polyurethane, the mechanical properties and storage modulus were enhanced compared with those of nonionic polyurethane. The prepared calcium-containing polyurethane was evaluated for its blood compatibility. An evaluation of blood-material interactions revealed that the material is blood compatible and that the polymer does not induce any hemolysis.
