Hence, the stated in the present chapter results give purely practical as-
pect of such theoretical concepts as the cluster model of polymers amor-
phous state stricture and fractal analysis application for the description of
structure and properties of polymers, treated as natural nanocomposites. The
necessary nanostructure goal-directed making will allow to obtain polymers,
not yielding (and even exceeding) by their properties to the composites, pro-
duced on their basis. Structureless (defect-free) polymers are imagined the
most perspective in this respect. Such polymers can be natural replacement
for a large number of elaborated at present polymer nanocomposites. The
application of structureless polymers as artificial nanocomposites polymer
matrix can give much larger effect. Such approach allows to obtain poly-
meric materials, comparable by their characteristics with metals (e.g., with
aluminum).
