Abstract
The influence of cross-linking upon polarization and space charge is invest igated. PMMA samples of different cross-linking degrees were prepared. The samples were poled under several DC fields and temperatures. Space-charge m easurements were made by the thermal-step method. The 'cleaning' technique was used to separate dipolar phenomena and injected charge. The results sho w that cross-linking affects the state of polarization of the samples and c ould favour space-charge accumulation. (C) 1999 Society of Chemical Industr y.
