Abstract
The present invention relates to polyphosphate ester morpholides, compositions comprising mixtures thereof and thermoplastic resin compositions containing the polyphosphate ester morpholide composition as a flame retardant. The flame retardant compositions comprise mixtures of polyphosphate ester morpholides which are represented by the following general formula I:in which X is 1 or 2; Ris a C-Caryl group, an alkyl substituted C-Caryl group or a derivative thereof; Ris a C-Carylene group, an alkyl substituted C-Carylene group or a derivative thereof; n is the average number of morpholide repeating units, m is the average number of Rrepeating units, and n+m is 1 to 5. In accordance with the present invention, it is possible to provide a flame retardant thermoplastic resin compositions having improved flame retardancy even when small amounts of the flame retardant are used. The thermoplastic compositions according to the present invention also have a desirable balance of properties such as workability, impact strength, heat resistance, appearance and the like.
