Abstract
Tyre rubber developments were discussed in terms of a materials science approach taking into account polymer type, carbon black type, silica incorporation, tyre service characteristics and test methods. Comparative tables and graphs illustrated priority characteristics of tyres for different applications, effects of new types of carbon black, advantages and shortcomings of black and silica fillers, effects of degree of structure of black on compound and vulcanisate properties and recommendations for applications of recent grades of Russian polymers. 15 refs.

Abstract
Tyre cord and reinforcement of car and small truck tyres, and latex treatment of the cords, was discussed with respect to Russian manufactured tyres and tyres imported into the country. Tyre cords prepared from polyamide, polyester and steel were discussed with respect to numbers of layers in the tyre, and in terms of consumption. Monitoring and control of the latex coating process was also mentioned. 23 refs.

Abstract
Developments and use of petroleum process oils in rubber compounds used in the tyre industry was discussed. Influence of the aromatic content of oils on oil properties was graphically illustrated, and cancer risks of traditional and ‘new' oils were discussed. Properties of rubber test compounds containing traditional and new oils were discussed and tabulated. The effects of restrictions on the sales and export of Russian domestic oils due to the REACH control system were mentioned. 18 refs.

Abstract
Problems of toxic chemical release and carcinogen exposure during the manufacturing and to a lesser degree during the use of tyres, the latter primarily due to abrasion and waste disposal, were considered and discussed. Levels of various toxic substances in the air in different departments of a tyre factory were compared. Toxic substance release from styrene-butadiene rubbers, polyisoprene, carbon black, vulcanising agents and process oils were listed. Dust exposure in the mixing area found in Russia was compared with conditions in the United Kingdom. 39 refs.

Abstract
A review of moulding methods used in the tyre industry, and the types of tyres that may be made by the different techniques, is presented. Transfer moulding is of particular interest for many tyres, but further research and development of technological concepts is required to allow use of this technology for other than simple moulding such as solid tyres, curing bags, or vulcanised rubber parts. Other systems considered include injection moulding, showing various attractive features and limitations that were discussed, and liquid moulding of polyurethane tyres. Computer aided design and analysis of different moulding methods was applied to examine some moulding methods. 14 refs.

Abstract
The introduction and development of polybutadienes suitable for blending with various thermoplastics to modify their properties or for use as tyre rubbers, and based on a continuous technology utilising a lithium containing initiating system, is described. Properties of the polymers are tabulated, and examples of the properties of different blend ratios with polystyrene are given. 5 refs.

Abstract
Developments leading to the synthesis of silica-carbon nanocomposite fillers for use in ‘green' and winter tyres is reported and discussed. Thermo-oxidative pyrolysis of an aromatic feedstock with organosilicon compound additives was used produce the filler. Samples were examined using scanning electron microscopy, X-ray diffraction and energy dispersive X-ray spectroscopy, and sample properties were reported. Initial results from the use of these materials in standard rubber mixes were tabulated. 3 refs.

Abstract
Degradation studies on plastics and rubbers using a new techniques labelled as oblique cutting infrared analysis (OCIR) and derivatisation X-ray microanalysis (DXMA) were carried out. Tests on amino-alkyd paint films, the anionic electrodeposition epoxy coating of a two-layer film, plasticiser migration from polyvinyl chloride (PVC) and chloroprene rubber degradation were reported using OCIR. DXMA was demonstrated with studies of the degradation of PVC sheet materials backed with a polyurethane foam (used as car interior trim materials), and degradation of outdoor exposed polyethylene sheets. The value of these additional test methods in the analysis of various materials, especially when utilised with attenuated total reflection infrared spectroscopy and X-ray photoelectron spectroscopy, was demonstrated. 5 refs.
