Abstract: The instant invention is directed to novel compounds and the use thereof in producing polyurethane resins. The compounds generally correspond to the following formula: ##STR1## wherein n is an integer of from 1 to 5,R is a C.sub.1 -C.sub.5 alkyl groupY is a C.sub.1 -C.sub.5 alkyl group or a ##STR2## and Z is a ##STR3## where n=0 or 1, X is --O-- or ##STR4## and R' is an aliphatic group having from 1 to 15 carbon atoms and may contain ester, ether, or amide groups or tertiary nitrogen and, when m=0, R' may be a hydrogen atom.

Abstract: This invention relates to novel flame retarding agents and processes in which they are used in the production of polyurethanes. These compounds are represented by the general formula: ##STR1## wherein: A and L, which are identical or different, represent optionally branched C.sub.1 -C.sub.17 -alkyl groups or -OR groups wherein R represents an optionally branched C.sub.1 -C.sub.8 -alkyl group, andX represents hydrogen, halogen, an optionally branched C.sub.1 -C.sub.8 alkyl group, a C.sub.6 -C.sub.12 aryl or aralkyl group, NH.sub.2, CF.sub.3, CN, COOR', SO.sub.3 R', ##STR2## wherein: R' represents hydrogen or an optionally branched alkyl or cycloalkyl group having 1-10 C atoms andR" represents an optionally branched alkyl or cycloalkyl group having 1-10 C atoms.

Abstract: This invention relates to novel halogen-free flame retarding agents and a process in which they are used in the production of polyurethanes. These compounds are represented by the general formula: ##STR1## wherein: R.sub.1 represents C.sub.1 -C.sub.5 alkylene groups which may be branched,R.sub.2 represents C.sub.1 -C.sub.3 alkyl groups which may be branched or R.sub.1 OH andR.sub.3 represents C.sub.1 -C.sub.8 -alkyl, C.sub.1 -C.sub.8 -dialkylamino, C.sub.1 -C.sub.4 -oxyalkyl, C.sub.1 -C.sub.4 -thioslkyl, C.sub.6 -C.sub.14 -aryl or C.sub.7 -C.sub.15 -aralkyl groups or ##STR2## and A and L may be identical or different and represent C.sub.1 -C.sub.10 -alkyl groups, which may be branched, benzyl groups or OR groups, whereinR represents an alkyl group, with 1-8 C atoms which may be branched, or a benzyl group.
