Abstract

The efficiency of thermal stabilization of polyvinyl chloride films containing a calcium-zinc stabilizer with the addition of pentaerythritol, magnesium pentaerythritate and zinc pentaerythritate has been investigated. A high synergistic effect of the use of magnesium pentaerythritol was revealed during the thermal stabilization of the polyvinyl chloride – calcium-zinc stabilizer system with a 1:1 stearate ratio. The influence of composition’s changes on the thermal stability of the films is considered and an explanation of the observed changes is proposed. The mechanisms of thermal stabilization of PVC by magnesium pentaerythritol and zinc pentaerythritol are proved.
