The thermal degradation of fluorocarbon and fluorochlorocarbon polymers has been studied using dynamic thermogravimetry. The effects of silicate fillers, carbon black and the cross-linking reaction on the degradation parameters (temperatures, rates) and activation energies were found. Kinetic values were determined with the procedure of Freeman and Carroll via graphical and computer techniques.

Thermal degradation of uncrosslinked chloroprene rubber in presence of different amount of zinc oxide has been investigated. It has been found that the quantity of zinc oxide has an important influence on the character, temperature, the rate of destruction and thermal stability. It concerns especially the first stage of degradation connected mainly with elimination of chlorine.

The thermal degradation of chlorine-containing polymers used in a rubber technology has been investigated in a nitrogen atmosphere. The characteristics of degradation have been compared on the basis of thermogravimetry, carbon residues and chlorine elimination. The observed structure-dependent differences in degradation of the investigated polymers are discussed.
