Abstract

We have performed preliminary small angle neutron scattering (SANS) experiments on a series of solutions of zwitterionic telechelic polysterene (ZT-PS) of low molecular weight, with the general formula: Br^-Me ₃N⁺-C₆H₄-[CH₂CH(C ₆H₅)]_n-C(C₆H₅) ₂-(CH₂)₃-SO₃ ^-Li ⁺. In addition, preliminary SANS experiments were carried out. Polymers were dissolved in non-polar (toluene) and polar (cyclohexanone) solvents. Concentrations studied ranged from 0.5% gmol^-1 to 16.8% gmol^-1. We observed small differences in the structural factors above q = 0.5 Å^-1 depending on the type of solvent. Below q = 0.5 Å^-1 there is a significant upturn in the scattering, which changes with the concentration of the polymer and the type of solvent. Complementary SANS measurements showed a clustering effect for zwitterions in a non-polar solvent.
