Influence of the strength of polarizing electric field on free relaxation of electric birefringence in poly(butyl-isocyanate) solutions

- Free relaxation processes of PBIC macromolecules were studied by the EB method.
- The average relaxation time decreases with increasing of the field strength.
- The decline in electric birefringence can be passably described by a set of exponents.
- The increase of intramolecular mobility with increasing electric field was determined.
