An investigation was made of the effect of organosilicon and organometallic compounds on the weather resistance of systems based on chlorosulphonated polyethylene. The effects of modification with tetrabutoxytitanium, ethyl silicate, and titanosiloxanes on the water and acid resistance, the steam permeability, and also the resistance to UV radiation and elevated temperatures were studied. Chlorosulphonated polyethylene (CSPE) is widely used as a special-purpose material for the development of acidresistant, low-flammability composites. Such properties result from the presence in the CSPE of chloride and sulphochloride groups, and also from the absence of nonsaturation in the polymer chain. Furthermore, CSPE-based coatings are noted for a number of valuable properties such as low gas and steam permeability, resistance to ozone, retention of elasticity at subzero temperatures, and compatibility with many polymers and synthetic resins, which makes it possible to vary the properties of CSPE-based composites widely [3].

Investigations were made of the temperature dependences of thermal conductivity for specimens of polymer composite material in which epoxy novolac resin was used as the matrix and in which carbon nanotubes were used as the fillers. Investigations of the temperature dependences of the thermal conductivity of polymer composite materials containing carbon fibres were conducted on a special measuring system. A negligible increase in the thermal conductivity of the composites was shown.

The paper presents the eff ect of carbon nanofi llers on the physicomechanical and thermophysical properties of polypropylene. Eff ective methods for homogenizing the system with the introduction of nanofi llers are proposed. The possibility of using carbon nanofi llers to create composites based on polypropylene with a set of controlled properties is shown.

The dependence of the apparent density of oligomethylsiloxane-filler systems on the size of the microspheres and their bulk density was established. The acid-base method was used to determine the acidbase properties of the surface of fillers and to assess the interaction at the phase boundary.
