The chemical composition of the synthesised sulphurcontaining ketoesters was determined. The migration of the plasticisers into isooctane/toluene, water, sulphanol solution and circulating air was studied. The properties of PVC composites plasticised using these adducts were investigated, including mechanical properties, frost resistance, critical dissolution temperature, water absorption, volatile content, thermal stability, and fungal resistance. 6 refs.

Data are presented on the water wetting angle for LDPE with additions of the same polymer after phosphonation, adhesion of LDPE and its composites with oxidised PE to oxidised copper film, dependence of ratio of strengths of 1240 cm^-^1 band of epoxydiane resin to 1460 cm^-^1 band of PE on thickness of removed surface layer, kinetics of oxidation of stabilised films made of LDPE and LDPE with non-crystallising polar additives (NPAs), and cracking resistance of PE containing small amounts of phosphonated NPA. 20 refs.

2 Author(s): Smirnov Y N; Muradian V E; Shatskaia T E; Beliaeva E A; Kosolapov A F; Tang Son-Pei File size: 132K Page 2 of 5 The molecular-topological structure and strength properties of polyepoxy vinyl ester resin modified with PU rubber (a macro-diisocyanate prepolymer) were investigated before and after exposure to a hydrofluoric acid solution at 60 deg C. The bending coefficient or chemical resistance coefficient was found to reach a peak at about 6 wt % of the prepolymer. The crosslinked structure of all the resins studied was micro-heterogeneous in terms of the extent of crosslinking. Modification of the resins with small amounts of prepolymer increased the degree of crosslinking and lowered the proportion of topologically-defective micro-sections of the crosslinked polymer. Exposure of the resin specimens to HF was shown to cause a marked decrease of the content of topologically defective micro-sections in the structure of the polymer, thus increasing the overall level of crosslinking of the polymer. 15 refs.

The additives include silica, titanium dioxide, zinc oxide, zinc sulphide and molybdenum disulphide. The action of these aggressive factors on polymers containing such additives, especially in a nano-form, is shown to open up new and positive potential for targeted modification of the structure and properties of highmolec.wt. compounds. 26 refs.

3 Numerical modelling was used to study the temperature field in a diamond-containing composite material with an organic matrix. The main polymers used in the manufacture of diamond-based abrasive cutting tools are phenolic resins. An analysis was made of the influence of the thermophysical properties of the binder, and also of the coatings on the diamond grains, on the temperature field in the composite. The results of modelling of a non-stationary temperature field in the diamond tool composite are presented. 10 refs.

The liner was made of vertical strips of polymer mesh with horizontal corrugations. Pressure head loss and air flow rate were monitored. The potential use of the liner for evaporation cooling processes, e.g. in water recycling systems at factories and in mass exchange processes in chemical engineering, was examined. An important advantage of the proposed liner is the two-way flow of liquid and gas, together with the high phase contact area and the low cost and ease of both manufacture and installation. 7 refs.

PE film waste was used with AIC waste in the form of cacao husks, beet pulp, husks of buckwheat, rice, millet and sunflowers, and potato and maize pulp. Particular attention was paid to study of the physical/mechanical properties of filled biodegradable polymer composites. Mathematical modelling and tests on physical/mechanical properties suggested that beet pulp, cacao husks and rice husks were the most effective of these fillers for production of biodegradable polymer composites. Processes of biodegradation of polymer composites filled with AIC wastes were also examined. A mixed modifier based on a sorbent and bentonite was developed for production of biodegradable polymeric materials based on PE waste filled with 30-40% AIC waste. 2 refs.

It was shown that, in the presence of a plasticiser which lowered the solubility of the rigid blocks in the flexible phase of the polymer, there was an increase in the stability of the mechanical characteristics of the polymers on exposure to a humid atmosphere. 10 refs. (Article translated from Plast.Massy, No.7, 2010, p.8-11) Title: SYNTHESIS AND PROPERTIES OF POLYETHER SULPHONE KETONE TEREPHTHALOYL DI(P- OXYBENZOATES) Page Range: p.t/51-t/55 Author(s): Khasbulatova Z S; Shustov G B; Mikitaev A K File size: 111K A method was proposed for synthesising polyether sulphone ketones containing fragments of terephthaloyl-di(p-oxybenzoic)acid by polycondensation reaction. The structure of the polymers obtained was confirmed by elemental analysis and IR spectroscopy. Their properties were studied, including yield, reduced viscosity, Tg and weight loss, and the results are presented and discussed. The copolymers were shown to possess a combination of valuable physicochemical properties for use in various sectors of industry. 10 refs. (Article translated from Plast.Massy, No.7, 2010, p.11-15)

It was shown that the polymer could be obtained in high yield (about 80%) with the required content of epoxy groups (about 11 mol %) and possessing good solubility in water, with a molec.wt. of 9 x 10^3. The polymer yield was higher when the reaction was carried out in 1-butanol than when using ethanol as the solvent. Potential applications in medical and biological fields are considered. 3 refs.
