Abstract

1465014 Diphenylmethane diisocyanates IMPERIAL CHEMICAL INDUSTRIES Ltd 17 Feb 1976 [25 April 1975] 17240/75 Heading C2C The invention comprises a composition comprising refined diphenylmethane diisocyanates and a stabilizing amount of glycidol. The glycidol is preferably used in an amount of from 0À001 to 0À25% by weight of the diisocyanate. The diisocyanate may in addition contain an antioxidant, for example 2,6-di-t-butyl-p-cresol, 2,2<SP>1</SP> - dihydroxy - 3,3<SP>1</SP> - di - t - butyl - 5,5<SP>1</SP>- diphenylmethane, 6 - α - methylcyclohexyl- 2,4-xylenol, distearyl- and dilauryl-thiopropionates and triphenylphosphite.
