1316707 Polyhydroxyl compounds NAPHTACHIMIE 19 April 1971 [23 March 1970] 24895/71 Heading C2C [Also in Division C3] A novel compound that is liquid at ambient temperature, comprises at least one isocyanuric nucleus per molecule and a plurality of hydroxyl functions and secondary or tertiary amine functions outside the or each isocyanuric nucleus, and has a hydroxyl number of 300-700 and an N content of 9-24% by weight, is prepared by reacting together isocyanuric acid, formaldehyde and an amino alcohol in which the amine function is primary or secondary and optionally, reacting the resulting product with at least one alkylene oxide. A polyurethane may be made by reacting the above novel compound with a polyisocyanate (see Division C3).
