✦ Synopsis

Poly(viny1 formal) films have been grown from solution. The dielectric properties of the films have been studied in the frequency range 100 Hz to 1 MHz at temperatures from 300 K to 450 K.The plots tan 6 versus temperature show two relaxation peaks which are discussed in terms of the molecular structure.

Blends of native corn starch and poly(ethylene-co-vinyl alcohol) (EVOH), with starch : EVOH ratios of 1 : 1 (SE-50) and 2 : 1 (SE-67A, SE-67B), were processed into blown films. SE-67A had a higher glycerol and water content and was processed at 5ЊC higher than was SE-67B. The films were conditioned

Dielectric constant and dielectric loss have been studied for poly(tetrafluoroethy1ene-perfluorovinyl ether) (PFA) films over a wide temperature range in the frequency range 0.1-100 kHz. Two relaxation peaks were observed, one at room temperature (a,-relaxation) and the other in the range 170-140 K
