Abstract

Contour maps of dielectric loss tangent within the ranges 0.1Hz to 3MHz and -175degreesC to +190degreesC are presented for a commercial poly(ethylene terephthalate) (PET) in two initial states of crystallinity. Individual absorption regions resemble those for poly(butylene terephthalate) and are attributed to carbonyl-driven alpha- and beta-relaxation processes and to Maxwell-Wagner-Sillars polarizations. Possible causes are considered for the asymmetry and structure apparent in the alpha-peak of partially crystalline PET. (C) 2001 Society of Chemical Industry.
