5. Sacrificial and regenerative stabilizers

The above descriptions distinguish between two operating modes of the stabilization system:

  • the "sacrificial" system, in which the stabilizer is irreversibly destroyed in the act of stabilization;

    Embrittlement kinetics of PP stabilized with phenol or HALS at moderate temperature
