Through improvements on a fully commercial and automatic system measuring frequency andtemperature spectra of the complex elastic

dielectric

and piezoelectric constants of polymerfilms

the precision for measuring complex dielectric constants achieved 2‰ from original 1%.The complex dielectric constants of PVDF

VDF （95 ）/VF （5）

VDF （52）/TrFE （48） and VDF（47. 5）/TrFE（47. 5）/HeFP （5） over a range of-120-140℃

10-2-10

Hz were measured bythe described system. The diminution of chain regularity due to 5mol% vinyl fluoride in the chainof PVDF led to disappearing of α-relaxation and increase in T

（3℃） of VDF （95）/VF （5）.Because of the spatial impediment of 5mol% HeFP in copolymer chain

the Curie point of VDF（52）/TrFE（48） decreased by 30℃ and T

by 3℃. The behavior of dielectric relaxation indicatedthat 5mol% vinyl fluoride and HeFP made the relaxation strength of noncrystalline regionreduced

the activation energy of local relaxation increased and the relaxation time prolonged respectively.
