The growth of microscopic fungi on polymer materials leads to the change in physico-mechanical properties of the latter. The extent and character of the property variation are determined by qualitative and quantitative compositions of fungi metabolites taking part in the process of biodegradation. In the present work, it was ascertained that the change of mechanical and dielectric properties of polyamides, polycaproamide fibers, silicate glass threads and rubber occurs in the process of their biodestruction and under the action of individual fungi metabolites. The change in the physico-imechanical characteristics of the polymer materials takes place before the growth of microorganisms on them becomes visible. The authors offer to regard the variation of the physico-mechanical properties as a principle criterion of the resistance of various polymer materials to biodamages induced by microscopic fungi.

The lyophobization of a filler surface relative to a polymer-monomer medium and the introduction in a copolymr of units poorly solvatable with a solvent enhance the interaction of macromolecules with the filler, and thereby increase the structure formation of high-filled systems. The structure formation of systems was estimated by rheological methods.

The influence of fillers on rheological properties and structural-rheological states of polymer-monomer systems as models of polymerization filling has been studied. The structure of such systems is created not only due to the interaction polymer-polymer, polymer-filler but the contacts between the filler particles.
