The influence of aniles DL-camphor as N-[(1RS)-camphane-2-ylidene]-2-methylaniline, N-[(1RS)-camphane-2-ylidene]-2-ethylaniline and N-[(1RS)-camphane-2-ylidene]aniline on vulcanization and resistance of butadiene nitrile rubber based elastomers to thermal oxidative aging was studied for the first time. The prospects of using aniles DL-camphor as anti-aging agents have been established. The best effect is achieved when using N-[(1RS)-camphane-2-ylidene]-2-methylaniline in combination with an effective vulcanisation system including sulfur donors tetramethylthiuram disulfide, 4,4'-dithiodimorpholine, and N-cyclohexylbenzothiazole-2-sulphenamide.

The basic physicomechanical properties of dynamically vulcanized elastoplastics based on random polypropylene and nitrile butadiene rubber are considered. It is shown that the higher the concentration of nitrile groups in the nitrile-butadiene rubber, the higher the limiting concentration of the elastomer to appear rubber-like properties in elastoplastics. In order to improve the compatibility of the components of the mixture, a graft copolymer of polypropylene with methacrylic acid was used as a compatibilizer. In contrast to sulfuric vulcanization, peroxide one contributes to a signifi cant deterioration of the melt fl ow index of elastoplastics.

The paper presents the results of a study of the dilatometric properties of thermoplastic elastomer nanocomposites based on mixtures of random polypropylene, nitrile butadiene rubber, a compatibilizer - copolymer of polypropylene with maleic anhydride. Nanosized bentonite particles were used as a filler. The concentration of bentonite nanoparticles was varied in the range of 1.0-20 wt %. The values of the free and occupied specific volumes of nanocomposites were determined depending on the temperature and concentration of bentonite. The mechanism and kinetic regularities of the crystallization process of nanocomposites are established.
