The present invention provides resin compositions comprising a thermoplastic resin and at least one phosphoramide having a glass transition point of at least about 0&deg; C., preferably of at least about 10&deg; C., and most preferably of at least about 20&deg; C. The present invention also relates to articles made from the resin compositions. The present invention also provides methods to make the resin compositions-having improved heat properties over compositions known in the art.

Flame retardant resin compositions containing phosphoramides, and method for making

Sterically hindered phosphoramidates such as N,N&prime;-bis&lsqb;di-(2,6-xylenoxy)phosphinyl&rsqb;piperazine are prepared by the reaction of a sterically hindered diaryl chlorophosphate, such as di-(2,6-xylyl) chlorophosphate, with a basic nitrogen compound containing at least two basic N&mdash;H groups, preferably a heterocyclic compound such as piperazine, in a predominantly liquid, solvent-free reaction mixture. The reaction may be conducted in the melt or in the presence of a non-solvent carrier, typically an aliphatic hydrocarbon. An excess of the basic nitrogen compound is employed as an acid acceptor.
