Abstract

Vickers microharness, MH, measurements have been performed on samples of a plasticized amorphous copolyterephthalate with different diluent contents. The dependence of MH on contact time is explained in terms of the Eyring equation and it has been found that the activation volume increases abruptly in the vicinity of the glass transition. © 1993 John Wiley & Sons, Inc.
