1. Definitions

Stabilization is any modification of a material designed to increase its chemical stability under given conditions. Stabilization can be :

  • internally, it is the very structure of the polymer that is modified by copolymerization, grafting, substitution, etc. ;

  • external; it is provided by additives generally incorporated during shaping, possibly in the form of a masterbatch.

Internal stabilization is mainly used to slow down or inhibit the thermal degradation of polymers breaking down in chain reactions.
