The influence of sulfidation on the structure and properties of polyacetylene

Abstract

The structure and properties of polyacetylene obtained by dehydrochlorination of PVC before and after sulfidation were studied by DSC and FTIR spectra. The mol. structure and electron properties of sulfided polyacetylene were calculated by CNDO/2 MO. Sulfidation greatly affected the energy level band structure, especially the energy band near HOCO and LUCO. The presence of S also changed the elec. charge distribution in the polymer.

Key words: INFRARED SPECTROPHOTOMETRY, MOLECULAR STRUCTURE, CNDO APPROXIMATION, STRUCTURE AND PROPERTY CORRELATION, DIFFERENTIAL SCANNING CALORIMETRY, ELECTRONIC STRUCTURE, CURING, POLYACETYLENE

CLC Number:

O631.
