New principles and processes for the treatment of polymers and polymer-based composites are discussed. The controlled effects of physical and mechanical fields on the rheological properties of polymers are analysed as a promising method of developing new component forming techniques. The following topics are discussed: solid-phase extrusion and hydro-extrusion, the cyclic deformation of melts in shear, the interaction of transverse and longitudinal ultrasonic vibrations, and the preparation of ultra-strong films and fibres. The bibliography contains 64 references.

Methods of preparation of α-halogenonitroalkanes and their functional derivatives are surveyed, together with the chief results obtained for the geometric parameters, electronic structure, and ultraviolet, infrared, and nuclear magnetic and quadrupole resonance spectroscopy, as well as acid–base properties. Reactions involving reduction, addition at multiple bonds, substitution of halogen atoms and the nitro-group, and interaction with diazoalkanes are analysed, and the most important mechanisms are discussed. Data are given on the toxicity, physiological activity, and practical use of these compounds. A list of 316 references is included.

The review gives for the first time a systematic account of the extensive literature data on the chemistry of aliphatic nitrosamines. A separate chapter summarises the work on the physical properties, structure, and spectra of N-nitroso-derivatives. The chemical behaviour of the nitrosamines is determined largely by the characteristics of the p–π-conjugation in the fragment. The principal chemical reactions of nitrosamines are treated from this standpoint: the denitrosation reaction, the formation of complexes, the cyclisation to sydnones and sydnoneimines, and the synthesis of lactams. In conclusion, certain aspects of the practical applications of nitrosamines are considered. The bibliography includes 272 references.

Methods of making primary aliphatic nitroamines are considered. In addition to the well-known traditional methods for the preparation of nitroamines, little known methods for making them are examined and prospects for their further development are discussed. This review is the first attempt in the world's literature to systematise the wealth of published material on primary aliphatic nitroamines. The literature is covered up to the end of 1967 or beginning of 1968. There is a bibliography of 207 references.

The review deals with the methods of synthesis of aliphatic diazoketones and gives a systematic account of the extensive literature data on their chemistry. The work on the physical properties, structures, and ultraviolet, infrared, and NMR spectra of diazoketones is summarised in a separate section where problems of p–π conjugation and rotational isomerism are also discussed. The concluding section deals with the hitherto few but interesting data on the biological activity of diazoketones. The bibliography includes 295 references.
