| titleOfInvention | Polyhydroxyl compounds containing phosphonormamidine groups |
| abstract | The present invention relates to new polyols modified by phosphonoformamidine groups, to a process for the preparation thereof and the use thereof as starting component for the preparation of preferably foamed polyurethane plastics. n The process involves (A) reacting diisocyanatocarbodiimides corresponding to the following general formula: n n OCN--R.sup.2 --N═C═N).sub.m R.sup.2 --NCO n n at a temperature of from about 25 to 130° C., optionally in the presence of an inert solvent, with polyhydroxyl compounds corresponding to the following general formula: n n A--OH).sub.n n n in an OH/NCO-ratio of from 1.2:1 to 30:1 to form a polyhydroxyl compound containing carbodiimide groups and (B) completely or partially reacting the carbodiimide groups remaining in the product of step (A) by means of a basic catalyst at a temperature of from 25 to 150° C., optionally in the presence of an inert solvent, with a phosphite corresponding to the following general formula: ##STR1## to form phosphonoformamidine groups, and (C) distilling off the inert solvent, if used; wherein n m represents a number of from 1 to 10, and n R 1 represents a C 1 -C 18 aliphatic, C 4 -C 15 cycloaliphatic or C 6 -C 15 aromatic or araliphatic radical which may optionally contain a double bond and/or be branched and which may optionally be substituted by a group selected from the group of hydroxyl or trifluoromethyl groups, fluorine, chlorine, bromine or iodine; n R 2 represents a divalent aliphatic, cycloaliphatic, aromatic or araliphatic radical having from 4 to 25 carbon atoms obtained by removing the isocyanate groups from a diisocyanate; n A represents an n-valent radical of the type obtained by removing the hydroxyl groups from a polyhydroxyl compound having a molecular weight of from 62 to 6000; and n n represents an integer of from 2 to 8. |
