Abstract
Zinc oxide was treated with a coupling agent (neopentyl(diallyl)oxytrineodecanonyl titanate)) (LICA 01) and the effect of the treatment on the mechanical properties of polychloroprene and NR filled with the zinc oxide investigated. The tensile strength, modulus at 100% and 400% elongation, Young's modulus and hardness of the rubbers filled with the treated zinc oxide were compared with those of rubbers containing untreated zinc oxide and fracture surfaces of the filled vulcanisates analysed by scanning electron microscopy. 16 refs.

Abstract
The advantages of the internal mixer are demonstrated using, as examples wood polymer composite compounding, thermoplastic vulcanisate production and brake and friction linings fabrication. Particular attention is paid to intermeshing rotor geometry with emphasis on its superior cooling performance and greater dispersing power. Advantages highlighted include higher output rates, process flexibility and no need for a premilling process. 8 refs. (Article translated from Gummi Fasern Kunststoffe, No.8, 2008, p.509-515))

Abstract
The results are reported of a study of the photoluminescence, ionic conductivities and Tgs of thermosetting ionic PU elastomers containing sodium sulphonate groups and low molec.wt. organic dyes, such as 6-aryl2H-pyrone derivatives. Investigative techniques employed were DSC, complex impedance measurements and fluorimetry. The results are discussed in terms of dye emission, effects of ionic group and dye content on PU properties, PU photodegradation and dye-polymer interaction. 23 refs.

Abstract
The crystallisation of PTFE under the action of ionising radiation was investigated using a calorimetric method, which enabled radiation-initiated processes in polymers to be studied directly during gamma-irradiation of specimens according to the additional evolution of heat accompanying these processes. The data obtained were used to derive a kinetic model of the formation of a new crystalline phase during gamma-irradiation and a quantitative criterion characterising its degree of conformational ordering proposed. 17 refs.

Abstract
Polyvinyl chloride plastisols were filled with up to 5 wt.% of diatomite or diatomite impregnated with spect hydraulic fluid and the flammability and physicomechanical properties of the filled PVC plastisols investigated. Plastisols containing diatomite possessed high fireproof and physicomechanical properties and those containing diatomite impregnated with hydraulic fluid had even higher fire resistance. 12 refs.

Abstract
Composites based on hydrolysis products of collagen and hydroxyethyl cellulose and plasticised with glycerin were cast into films on glass and PE substrates and the relationship between the composition of the composite, amount of structure-forming agent (Nord) and characteristics of the films and solutions investigated. The effects of the main components and additives on the viscosity, tackiness, transparency and water resistance of the composites were examined and the suitability of the films for use alone and for cosmetics applications considered. 4 refs.

Abstract
Glass fibre-reinforced composites were fabricated using epoxy-based vinyl ester and epoxy fumaric resins (Dion 9100, Dion 9700 and Dion 6694) and evaluated as chemically-resistant components at the Novokuibyshev Oil Refinery. Data on the properties (including density, viscosity, gel time, heat stability, mechanical properties and porosity) of the chemically-resistant resins, composite linings and laminate structures are included. 5 refs.

Abstract
Composites were fabricated from waste umbrella fabric consisting of PETP, polycaproamide and an additive and their physicomechanical properties investigated. The effect of the addition of a vinyl oligomer (alpha,omega-bis(vinyl-o-phthalate ethylenehydroxy)ethylene) on the properties of the composites was also investigated. Properties evaluated included tensile stress, yield point upon elongation, elastic modulus, impact strength and Brinell hardness. 8 refs. (Article translated from Plast.Massy, No.9, 2007, p.48-49)

Abstract
The problems associated with the reprocessing of PVC waste are considered followed by ecological and economic assessments of Solvay's Vinyloop dissolution method in comparison with landfill for dealing with waste PVC, such as waste cable products. Diagrams illustrating the relationship between the effect on the environment and cost of the methods investigated are included. The ecological assessment focuses upon primary energy consumption, global warming potential, oxidation potential, emissions during reprocessing and harmful waste products.
