摘要:
Polymeric stabilizers with a polysiloxanic structure contain sterically hindered phenol groups and reactive groups capable of binding themselves to the polymeric structure to be stabilized. These polymeric stabilizers are particularly suitable for applications which require the non-extractability of additives due to solvents, fats or soaps.
