Polyhydroxyl compounds containing guanidine groups useful in preparation of polyurethane foams

Claim 1

Compounds containing at least two terminal hydroxyl groups and having a molecular weight of from 400 to 15,000, which compounds comprise segments in their molecular structure corresponding to the following general formulae: ##STR5## wherein R 1 represents hydrogen or 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 contain one or two substituents selected from the group consisting of hydroxyl, mercapto, secondary amino, sulphonic acid ester, phosphonic acid ester, carboxylic ester, siloxane, trifluoromethyl or nitrile groups, fluorine, chlorine, bromine or iodine or R 1 represents one of the radicals: ##STR6## or R 1 together with R 3 and the nitrogen atom forms a 5- or 6 membered heterocyclic ring optionally containing as additional hetero atoms an oxygen atom or up to two nitrogen atoms; R 2 represents a divalent aliphatic, cycloaliphatic, aromatic or araliphatic radical containing from 4 to 25 carbon atoms obtained by removing the isocyanate groups from a diisocyanate; R 3 represents a monovalent or -- in the form of a bridge to other guanidine groups -- divalent or trivalent 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 contain one or two substituents selected from the group of hydroxyl, alkoxyl, mercapto, secondary amino, sulphonic acid ester, phosphonic acid ester, carboxylic ester, siloxane, trifluoromethyl or nitrile groups, fluorine, chlorine, bromine or iodine; or one of the radicals: ##STR7## or together with R 1 , the nitrogen atom and, optionally, the nitrogen atom of another guanidine group forms a 5- or 6-membered heterocyclic ring optionally containing as an additional hetero atom an oxygen or nitrogen atom; R 4 represents an aliphatic, cycloaliphatic, araliphatic or aromatic radical containing from 1 to 15 carbon atoms; R 5 represents an s-valent aliphatic, cycloaliphatic, araliphatic or aromatic radical containing from 1 to 15 carbon atoms; 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; represents an integer of from 2 to 8 represents an integer of from 1 to 3; represents an integer having a value of from 0 to (n-1); and k represents 0 to 1.
