Abstract

The unperturbed chain dimensions of atactic near-monodisperse poly(ethylethylene) were evaluated in different Θ-solvents over the temperature range 10-80 C. Radii of gyration, measured by small angle neutron scattering (SANS), were found to increase with increasing temperature and led to a value of 0.4 × 10-3 deg-1 for d In 〈R2〉r/dT; behavior which replicates that seen in the melt state via SANS and thermoelastic measurements. Those findings are contrary to those from intrinsic viscosity measurements.
