摘要

The dielectric loss factor and permittivity of a series of 1

2-polybutadienes with different contents of 1

2-units and different contents of syndiotactie 1

2-units were determined over a frequency range from 30Hz to 100KHz at different temperatures. The WLF equation was evaluated for various samples with Tθ at 100KHz as a reference temperature and the master curves of various samples have been constructed

which are in accordance with those calculated by Havriliak-Negami equation. The frequency dependence of the dielectric relaxation of 1

2-polybutadienes was investigated over a frequency range from 100 Hz to 1012 Hz in lerms of the experimental data and the master curves.
