| abstract |
This invention relates to novel 4-hydroxy-5-(substituted phosphinyl)ethyleneureas of the general Formula I <IMAGE> I to methods of making the same, to flame resistant compositions containing such compounds and to the use of compositions containing such compounds to impart flame resistance to cellulose and cellulose containing materials. In the compounds of the Formula I X or Y may be hydrogen or alkyl, R1 and R2 may be the same or different radicals including alkoxy, cycloalkoxy, aryloxy, arylalkoxy, alkyl, aryl as well as such radicals containing substituents such as halogen; in addition, R1 and/or R2 may be hydroxy. |
