Relaxation processes in polystyrene matrices

Abstract

Dielectric absorption of aromatic and aliphatic molecules containing the rotatable substituent group and of some analogous rigid molecules in $olutions of polar solutes dispersed in an atactic polystyrene matrix are studied. Preparations of these solutions as solid disks and the dielectric measurements using a General Radio 1615-A capacitance bridge and a Hewlett-Packard Q-meter with appropriate temperature-controllable cells are described.
