| abstract | 1480560 Degrading polyurethane polyisocyanurate foams BRIDGESTONE TIRE KK 19 Dec 1975 [19 Dec 1974] 52054/75 Heading C3R Rigid polyurethane or polyisocyanurate foams, are degraded into a polyol-containing homogeneous liquid composition, which is suitable for the production of rigid polyurethane foam by treatment at a temperature of 150‹ to 220‹ C. in the presence of a mixture of (a) an aliphatic diol having from 4 to 7 carbon atoms and a boiling point above 160‹ C. and (b) a monoalkanolamine having from 2 to 8 carbon atoms in an amount of 1 to 20% by weight of the mixture. Preferred diols are diethylene glycol, dipropylene glycol, 1,4-butane diol and 1,5- pentane diol. The preferred monoalkanolamine is monoethanolamine. The process is particularly applicable to foam which is in chip or waste form. |
