| Description
| - Flexible polyurethane foam scrap was chemically decomposed via glycolysis. Optimal reaction conditions for glycolysis were determined: temperature, 2208C, polyurethane/glycol ratio, 1:1; reaction time, 2.5 hr; diethylene glycol or dipropylene glycol as reagents. Two types of polyurethane scrap were tested; both gave the recycled polyols having the same properties, which is advantageous for possible applications on a commercial scale. A mixture of the virgin and recycled polyols (up to 36 wt%) was used to manufacture rigid polyurethane foams. No undesirable influence of the recyclates on process parameters (cream time, gel time) was found. The end-use properties of the rigid foams were practically the same in the whole range of tested concentrations of recyclates. A fine cellular structure of all tested foams was found.

- Odpadní měkké polyurethanová pěna byla podrobena glykolytickému rozkladu. Byly stanoveny optimální podmínky glykolýzy: teplota 220°C, polyurethan/glykol hm. poměr 1/1, reakční čas 2,5 h, diethylenglykol nebo dipropylenglykol jako reagenty. Byly odzkoušeny dva typy polyurethanového odpadu a z obou lze získat recyklované polyoly, které mají shodné vlastnosti, což je výhodné z hlediska jejich možné aplikace v průmyslovém měřítku. Směs panenského a recyklovaného polyolu (do 36 hm.%) se použila pro přípravu tvrdých polyurethanových pěn. Nebyl pozorován žádný nežádoucí vliv recyklátu na procesní parametry (čas do začátku vypěňování, čas gelace). Koncové vlastnosti tvrdých pěn byly prakticky shodné v celém testovaném koncentračním rozsahu přidávaných recyklátů. Struktura všech testovaných pěn obsahovala dostatečně jemné buňky. (cs)
