In the review physical and chemical aspects and technological parameters of the rubbers production processes from industrial latex with application of ammonium halogenides, tetraalkylammonium salts, poly-(N,N-dimethyl-2-oxypropyleneammonium) chloride, poly-N,N-dimethyl-N,N-diallylammonium chloride, and his copolymer with SO2 are considered. A significant ecological effect of polymeric flocculants application is shown.
Prospects of recycling of waste products of fibrous materials (cotton, viscose, kapron) for obtaining of elastic composite materials are shown by creation of fibre-latex composition with subsequent coagulation and vulcanization of the filled rubber. The optimum contents of the fibre and its length is determined.
In this work the synthesis technology of zinccontaining polymer - inorganic composite on the basis of products of secondary raw material processing at joint precipitating with carbamide and formaldehyde (ZnCFO) is described. The structure and properties of ZnCFO are investigated by the differential-thermal analysis, electronic microscopy, and IR-spectroscopy. The action of ZnCFO as vulcanization active component of elastomeric compositions on the basis of rubbers of general and special purpose with various vulcanization systems is investigated.
The influence of a carbon nanomaterial obtained in a high-voltage discharge plasma on the endurance of elastomer compositions has been investigated. Complex tests of elastomeric compositions with highly dispersed carbon additives allowed us to confirm the model of nonlinear elastic deformation of macromolecules and adhesion between the elastomer and the nanoparticles.
