Optimal reaction conditions for glycolysis were determined: temperature, 220°C, 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.
