Abstract
The mixtures of PE-80% GeO2, Mg, MgO and NaCl were deformed at pressure 0.5-4.0 GPa and investigated by DSC-method. Enthalpy of polymer melting was more than 300 J..g-1. Exothermal processes were fixed on thermogrames of deformed mixtures. Such effects are соnnected with interface interaction in heterogeneous mixtures.

Abstract
In the paper the rheological and mechanical properties of composites based on low-pressure polyethylene with nano-additives. The influence of nanoparticles both on the rheological and mechanical properties of polyethylene, and the dependence of these properties on specific surface area of nano-additives and the presence of modifier.

Abstract
Using the acceptor-catalytic method of polycondensation were obtained aromatic copolycarbonates containing diсhloroethylene groups in the main chain on a basis 4,4'-isopropylidenediphenol and 1,1-dichloro-2,2-di (4-hydroxyphenyl) ethylene. Some physical and chemical characteristics of the received polyethers are investigated. It is shown that copolycarbonates have high heat and fire resistance.

Abstract
The rheological characteristics of the polysulfone melt domestic brand PSF-190 with processing additives of different nature: silsesquioxane, fluoride and polimethylsiloxan. The curves flow PSF-190 at different additives with their contents in a wide range of temperatures, velocities and shear stresses. It was shown that the functional properties of the additives essentially depend on their thermodynamic compatibility with PSF-190 at high temperatures (290-320oС) content and solubility. It found that the most efficient (by 2.5 times) reduces the viscosity of administering PSF-190 2.5 wt. % silsesquioxane additive.

Abstract
The results of investigation of influence of the natural filler of vesuvianite on basic physical-mechanical properties of the polymer composites on the basis of various types of polyolefins have been presented. It has been shown that an availability of kaolinite (nano-clay) in composition of vesuvianite favors essential improvement of melt flow index even high contents of disperse filler in the polymer composites. A dependence of strength of the composite from concentration of vesuvianite passes through maximum depending on type of polyolefin.

Abstract
The way of obtaining adhesive compounds with increased strength is considered. For bonding polymer adhesives are used, modified by the influence of magnetic ultrasonic field. During processing of adhesives in ultrasonic magnetic field structural construction of adhesive macromolecules varies towards ordering, which leads to creation of more stable compounds on the basis of these adhesives. Also internal stresses in the glue line reduce, the effect of adhesive wetting of the surface of substrates increases.
