Polymeric materials have
many merits, but researchers continue to seek new polymers with even better
properties. One of the ways of obtaining novel polymer materials with improvedproperties which cannot be produced by direct polymerization is to mix polymers
with various kinds of fillers at various weight ratios.

An important aspect of
this method is the fact that it reduces manufacturing costs. The properties, in
particular, the mechanical ones, of filled polymers depend to a large extent on
the size, shape and distribution of the particles of the filler in the polymer
matrix, as well as on the quality of adhesion between the filler and the matrix.
Commonly, the weight content of the filler ranges from several to several dozen
percent (60 or more).Such composites are prepared by mixing in mills or in the
plasticizing systems of processing machines such as extruders and injection
moulding machines.
