The importance of developing GOST standard specifications for the quality control of different grades of synthetic rubber produced in Russia, incorporating standard elastic strength and rheometric characteristics, is shown. Here, ISO and ASTM test procedures must be used, as well as positive features of Russian technical documentation. The need for and the possibility of producing and certifying home-produced reference ingredients and carbon black are also shown. The creation of a unified base of reference materials (ingredients, carbon black, etc.) will make it possible to increase the reliability of product quality control at synthetic rubber, tyre, and mechanical rubber goods plants.

Characteristics of surface orientation of cis poly(butadiene) elastomers with covalent crosslinks were studied with data from MPTIR ir spectroscopy and electron microscopy. It was shown that the supramolecular structures observed in electron photomicrographs of uniaxially stretched elastomer surfaces and their spatial reorganization correlate completely with changes in dichroism of a series of absorption bands in the MPTIR ir spectra. It was established that the maximal dichroism values in the MPTIR spectra correspond to orientation of coarse fibrillar forms, and the subsequent dichroism decline, corresponds to their deorientation. It was shown that, according to the extent of deorientation of the coarse fibrils, an increase in the cross section of the thin fibrils occurs with sharper margins separating them from the disordered part of the polymer; it was established by this that in the MPTIR spectra Rxy is partly increased, the intensity of a series of vibrations grows, and new absorption bands appear. The indicated facts are explained as due to intrafibrillar crystallization.
