Cross-linking yields a rigid polymer network with two types of dipoles: those already cross-linked and therefore thermally stable and those not as yet cross-linked and therefore fast relaxing. The combination of isothermal and thermally stimulated measurements allows for a complete characterization of dipole relaxation in the two sample polymers.endielectric relaxationnonlinear opticsoptical polymersthermally stimulated currentscross-linking degreepoled nonlinear optical polymerthermal dipole-orientation stabilityisothermal measurementsthermally stimulated measurementsdipole relaxation621541journal article
