| titleOfInvention | Modified organic polyisocyanate compositions |
| abstract | Organic di- or poly-isocyanates are restrained from becoming coloured or are decolorized by addition of 0.001-1% of a compound containing 1-5 ethylene imine rings in the molecule. Many such compounds are specified, including compounds containing ethylene imine rings and oxygen, sulphur, phosphorus, arsenic, antimony, titanium, boron or silicon atoms. The ethylene imine compounds may be used alone or in association with 0.01-0.5% of a phenolic compound, a number of which are specified. Comparative examples of the use of many of the ethylene imine compounds in the treatment of 4,41-methylene-bis-(phenylisocyanate) and tolylene diisocyanate are given. Other di- or polyisocyanates which may be treated are also specified, including chlorobenzene-2,4-diisocyanate.ALSO:In the manufacture of polyurethane or polyurea resins from organic di- or poly-isocyanates and compounds containing a plurality of hydroxyl or amino groups, the tendency of the products to become discoloured is restrained by using isocyanates which have been pretreated with 0.001-1% of a compound containing 1-5 ethylene imine rings in the molecule. Many such compounds are specified, including compounds containing ethylene imine rings and oxygen, sulphur, phosphorus, arsenic, antimony, titanium, boron or silicon atoms. Alternatively, the compound containing ethylene imine rings may be included in the reaction mixture. From 0.01 to 0.5% of a phenolic compound, based on the isocyanate, may be used in association with the compound containing ethylene imine rings. A number of suitable phenolic compounds are specified. Examples are given of the preparation of resins from (1) polytetramethylene ether glycol, tetramethylene glycol and 4,41 - methylene - bisphenylisocyanate) preheated with tris-(1-ethylene imine) phosphine oxide, and (2) propylene oxide addition product of trimethylolpropane, trichloro-monofluoromethane and tolylene diisocyanate which has been pretreated with ethylene glycol bis-(diethylene imino thiophosphate), the product of this example being a foamed resin. |
