Abstract
Naphthenic oils with a broad range of viscosities and different physical properties were used as extender oils in tyre formulations based on emulsion SBR filled with carbon black and on solution SBR with silica as filler. The effect of extender oil on compounding and vulcanisation were studied and the properties of the tyre rubber compounds determined. The results obtained were compared with those for rubber compounds containing a treated distillate aromatic extract and a distillate aromatic extract.

Abstract
Butadiene was polymerised in the presence of a neodymium versatate-diisobutylaluminium hydride-hexachloro-p-xylene catalyst system and the effects of monomer and catalyst concentrations on polymerisation kinetics and the molecular characteristics of the polybutadiene formed investigated. It was found that monomer and catalyst concentrations mainly determined the level of average molec.wts. and polydispersities of the polymers and had little effect of polymerisation kinetics. 8 refs.

Abstract
The mechanism of adhesion of chlorine-containing polymers, including polytrichlorobutadiene and copolymers of trichlorobutadiene with derivatives of alpha-cyanoacrylic acid, was investigated in the bonding of various substrates, including metals and rubbers. Data are including showing the dependence of pull strength of rubber compounds based on SKI-3 on the content of reactive functional groups in polytrichlorobutadiene, dependence of pull strength of rubber-to-metal specimens bonded with the polytrichlorobutadiene and a copolymer thereof with ethyl cyanoacrylate and the influence of ageing on the bond strength of rubber compounds based on SKN-18 and SKN-40 nitrile rubbers to steel. 1 ref.

Abstract
The composition of water-soluble ash and the effect of process factors on ash content in the production of SKI-3 isoprene rubber for cables were investigated. It was found that a reduction in water-soluble ash could be achieved by reducing antiagglomerator dose and that SKI-3D-dielectric grade rubber could be produced in parallel with SKI-3 on a separate production stream with control of rubber load on the drying unit and antiagglomerator dose. 7 refs.

Abstract
The results of tests on vulcanisates (produced from model rubber mixes containing carbon black or shungite) carried out using the NanoTest 600 measuring unit are reported and correlated with data obtained from standard physicomechanical tests conducted on a UTS-10 tensile testing machine. The possibility of using the results obtained from the NanoTest equipment to assess filler-elastomer matrix interaction, filler-filler interaction, homogeneity, resilience and elasticity is demonstrated. 17 refs.

Abstract
Fouling and cleaning of compression moulds are discussed and the use of semi-permanent barrier lubricants based on solvents and waterproof coatings for protecting against corrosion, which results in rapid mould refouling, is evaluated. Tests are carried out on rubber mixes based on NR and bromobutyl rubber using moulds made from low-carbon steel, which are cleaned with solvent and coated with a water-soluble barrier lubricant based on polysiloxane. The moulds are also sand blasted following compression moulding, treated with the protective coating and tested for corrosion resistance. 1 ref.

Abstract
Reclaim from protective silicone coverings of spent and defective electrical insulators was mixed with virgin silicone rubber and protective coverings for high-voltage insulators fabricated therefrom. The mechanical and electrical properties of the protective coverings were investigated and the suitability of the protective coatings containing 20 wt.% of reclaim for producing economically and environmentally friendly protective coatings established. 7 refs.

Abstract
An investigation was carried out into EPDM mixing conditions to improve dispersion of multiwalled carbon nanotubes therein. It was found that a lower roll temperature was effective in improving nanotube macrodispersion while a higher roll temperature was effective in improving microdispersion. Excellent dispersion of nanotubes was achieved by two-stage mixing in which mixing at low temperature was followed by high temperature mixing. The findings of the investigation were confirmed by conducting studies on nanotube-filled NR composites. 9 refs. (Article translated from Nippon Gomu Kyokaishi, No.6, 2009, p.247-251)

Abstract
An investigation was carried out into the possibilities and methods of controlling the physicomechanical properties of reinforced thermoplastics. Known methods were identified and classified and the effectiveness of these methods to provide the desired physicomechanical properties evaluated. Criteria employed in the classification were signs of imperfections in reinforced thermoplastics of specified composition and structural reinforcement, typical examples of which were porosity, phase interface defects, non-uniformity of reinforcement composition and structure and residual processing stresses. 22 refs.

Abstract
The effect of molec.wt. on the molecular mobility, transition temperatures, relaxation and physicomechanical properties of PMMA was investigated. The data obtained revealed that it was possible to use PMMA with low molec.wts. as plasticisers and to produce bimodal systems or systems with specified MWDs possessing good processability and specified processing and service properties. 13 refs. (Article translated from Plasticheskie Massy, No.12, 2008, p.9-13)
