Morphological analysis of ionomers. Final report, January 1, 1992--August 31, 1995
This report describes three studies on ion containing polymers. (A) Extended X-ray absorption fine structure studies of ionomers investigate lightly sulfonated polystyrenes and polyurethane cationomers. In the first material, the nickel, zinc and cadmium-neutralized ionomers were investigated and the details of the cation local environment was elucidated through the use of the simulation package (FEFF5{reg_sign}). For the lightly sulfonated polystyrenes, the availability of a detailed ab initio simulation package, FEFF5{reg_sign} allowed the determination of the local structure at a level of detail not previously possible. (B) Nuclear magnetic resonance of lightly sulfonated polystyrene is studying the local environment of the cation in sodium-neutralized lightly sulfonated polystyrene. (C) Solution studies of carboxy-telechelic polystyrene ionomers are using small-angle neutron scattering to explore the role of temperature in solutions of sodium-neutralized carboxy-telechelic ionomers in toluene.
