PREFACE
Modern technologies of large-scale production processes are based on the strategy of a multistage
approach to the final product. This is the historical course of development of the metallurgical indus-
try: first, iron-ore is transformed into cast iron, then the latter is converted into steel of different
types; this steel is then rolled and the final article only at the last stage by machining the rolled pro-
files. The same general approach is used in the building materials and construction industries. This is
also true for polymeric materials. A monomer is first converted into a polymer; then raw material in
the form of granules or powder is prepared pounding of the polymer with various additives.
Only after that is the polymeric material processed into a final article by extrusion, injection molding
or other processing methods. The heart of this multistage process consists primarily in the separa-
tion in place and time of consecutive processing steps in pass
