Excretion kinetics of the rubber anti-oxidant N-isopropyl
Summary. Sixteen rubber vulcanizers using IPPD as anti-oxidant were monitored for the presence of the parent compound in the urine during two consecutive working weeks using HPLC for analysis. At least two components in the excretion kinetics could be demonstrated: a fast one, as end-shift urinary concentrations significantly exceeded before-shift...

Grafting antioxidants VII. Grafting of antioxidants
CONCLUSIONS (1) Macromolecular antioxidants can be ob- tained by grafting low molecular weight antioxidants containing amino or thiol groupings to epoxidized natural rubber. (2) Antioxidants obtained by derivatization of ENR with bis-(N-isopropyl-N'-phenyl-p- phenylenediamine)disulfide have a very high activity in protecting rubbers and rubber vulcanizates against thermooxida- tion and mechano-thermal degradation.

Grafting antioxidants; Part VI—grafting kinetics of 35S
The grafting kinetics of bis-(N-isopropyl-N-phenyl-p-phenylenediamine) disulfide to polyisoprene and styrene-butadiene rubber was investigated using the 35 S labeled disulfide. The labeled compound was synthesized by reacting 35 S 2 Cl 2 with the diamine. The grafting was induced by thermal treatment.

Rubber Antioxidant IPPD(4010NA)
Properties: A high activity antioxidant for matural and synthetic rubber provides powerful antiozonant and antioxidant properties with excellent high temperature, fatigue and flex resistance to rubber compounds.While used primarily for ozone resistance, it is a more active antioxidant than quinoline or diphenylamine based antioxidants. The product (alone or in combination with TMQ) provides ...

Kinetics of the Thermal Decomposition of n-Propyl
The kinetic behaviour is unusual, although different, in the two cases. In both cases the observed results can be explained by postulating complex formation between the azo compound and a product of the decomposition.

Antioxidants Explained in Simple Terms
Antioxidants in foods. Antioxidants are essential for the survival of all living things. Your body generates its own antioxidants, such as the cellular antioxidant glutathione. Plants and animals, as well as all other forms of life, have their own defenses against free radicals and oxidative damage.
