Savchenko B. Physical and chemical conversions in condensation polymers and blends recycling processes

Dissertation is concern about technological and scientific aspect of recycling and modification of basic condensation polymers which is based on modern modification techniques and processes - solid state polyaddition, reactive extrusion with functional monomers, controlled depolymerization, polymer blends preparation and trans molecular reactions. Based on scientific research and practical implementation new and effective technological processes was developed which is able to save and apply valuable raw materials and reduce industrial influence on nature environment. For recycling of polyester waste new depolymerization techniques was developed which is able to produce resin material for different industrial applications. First in local practice, complex rheological and thermal properties of wide range of condensation polymers was researched and systematized.
