INDUSTRIAL, liquid-phase oxidation of paraffin hydrocarbons into synthetic aliphatic acids (SAA) is carried out using a manganese-potassium catalyst [I] This catalyst fulfils several functions, particularly catalysis of oxidation, taking part in the

The EPR method is used in a kinetic study of the addition of 2,2,6,6-tetramethyl-4-benzoylhydroxypiperidine-1-oxyl () to the double bond of α-methyl-2,6-di-tert.butylmethylene quinone in benzene (log (k1) = (2·2±0·6)-(29·0±4·0)/2·3 RT) and is

Disulphides catalytically break down tert-butyl and cumyl hydroperoxides. In chlorobenzene breakdown takes place by a bimolecular mechanism at a rate which is directly proportional to the concentration of hydroperoxide and disulphide; the rate consta

Kinetic studies were made of iniated oxidation of polyethylene and polypropylene in solution and solid phase. It was shown that, during oxidation of polymers in solution, chain breakage takes place by reaction between the inhibitor and peroxide macro

The authors examine and systematize the experimental data on the dynamics of movements of spin probes in polymers exposed to uniaxial stretching or all-sided compression. It is shown that these results may be explained both in terms of the thermodyna

In practical application, polymeric products are often subjected to mechanical stress. This can be connected both with changes in the rates of chemical reactions in the polymer, and with changes in the diffusion rates of reagents. Previously it has b

A study was made of kinetic regularities of the initiated oxidation of polyethylene and polypropylene in presence of 2,2,6,6-tetramethyl-4-benzoylpipyridine-l-oxyl. It is shown that the iminoxyl radical inhibits oxidation of the polymers by chain ter
