  • Polysiloxanic stabilizers containing sterically hindered phenol groups and reactive groups
    Patent number: 5326818
    Abstract: 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.

  • Siliconic U.V. stabilizers containing reactive groups
    Patent number: 5216103
    Abstract: Polymeric stabilizers having a polysiloxanic structure contain reactive groups which can be linked to the polymeric structure to be stabilized and sterically hindered piperidinic groups. These polymeric stabilizers are particularly suitable for the stabilization of organic polymers against U.V. radiation and heat, when it is required for them not to be extracted by solvents, fats or soaps.
