✦ Synopsis

Antimony tris(isooctyl thioglycolate) [Sb(IOTG)3 ] is a powerful thermal stabilizer for PVC, particularly if added in quantities up to 2% (m/m) with respect to PVC. During the stabilizing action, (IOTG)2SbC1 is formed while the rate of elimination of HCI from the polymer decreases appreciably. The thermal degradation is accelerated as (IOTG)SbClz appears. During long-term heat treatment of PVC mixtures stabilized with Sb(IOTG)3, the organoantimony compound decomposes and its activity decreases.
