AbstractThe present invention relates to the stabilization of a polymer by a stable free radical and in particular to the use of a stable free radical for inhibiting the degradation of a polymer by a mechanism which does not involve oxygen. This use can be carried out when the polymer is in the presence or in the absence of oxygen. The degradation which can be inhibited can be a depolymerization or a crosslinking.
