Abstract
Reversing-pulse electric birefringence (RPEB) of poly(γ-benzyl L-glutamate), [Glu(OBzl)]n, with a weight-average molecular weight of 1.71×105 was measured at 20°C and at 535 nm in helix-forming organic solvents in the low field strength region (0–5 kV cm−1), with an emphasis on the transient signal. The theoretical formalism was given for detecting the effect of an applied electric pulse field on reversible change in the electric and hydrodynamic properties of [Glu(OBzl)]n from the normalized signal profiles, areas, and initial slopes of an RPEB signal. A standard experimental procedure was given for unraveling the field-induced change of the electric and hydrodynamic parameters, by utilizing the areas of buildup (AB), reverse (AR), and decay (AD) processes at the limiting low field. The area ratio, AB/[(1/2)AR+AD]=1, should hold regardless of the degree of polydispersity of a sample, if no direct field effect on polymer conformation is present. The ratio was found to be 0.95 in cyclohexanone, 0.93 in 2-chloroethanol, 0.81 in pyridine, and 0.74–0.81 in chloroform, all being less than unity. Thus, the electric moments and/or the chain length of the [Glu(OBzl)]n helix were verified to change reversibly to varying extent during the electric field orientation.
