The dielectric constant and the electric birefringence of poly-7-benzyl-L-glutamate in ethylene dichloride-dichloroacetic acid mixtures have been measured aa functions of the solvent composition. Thew properties undergo a marked decrease with the addition of a small amount of dichloroacetic acid, aa
Prom the temperature dependence of ESR absorption intensity, it is shown that the intermolecular exchange interaction is ferromagnetic in the dilute mixed crystal and antiferromagnetic in the low-temperature phase of the pure crystals. The exchange energy is obtained as 2Jr= 1.5 + 0.7 meV and 2JAF=
## Abstract Precise measurements on the viscosities of the solutions of sodium carboxymethylcellulose in water and three ethylene glycol–water mixtures containing 10, 20, and 30 mass % of ethylene glycol have been reported at 35 °C. Isoionic dilutions were performed at total ionic strengths in the
