Optimization of Microwave Glycerolysis of Crosslinked Rigid PU Foams for Using Recyclate in Production
 Figalla, Silvestr ; Kučera, František (referee) ; Petrůj, Jaroslav (advisor)
The theoretical part summarizes the chemical recycling processes of polyurethane and polyisocyanurate insulation foams and methods of polyols preparation from their alcoholysates. Emphasis is placed on the use of microwave heating during depolymerization, as a perspective energy source for chemolysis processes. The practical part is focused on optimization of recyclates preparation derived from polyisocyanurate foams and polyethylene terephthalate by microwave enhanced glycerolysis. Recyclates obtained were verified for their workability and applicability in blends with virgin polyols in polyisocyanurate foam manufacture process.
