Claim:
1. A moldable thermoplastic flame retardant polymer composition comprising: a) a thermoplastic polymer, into which thermoplastic polymer has been compounded by melt processing without negatively impacting the physical, thermoplastic properties of the thermoplastic polymer, b) from 1% to 50%, by weight based on the total weight of the flame retardant polymer composition, of a flame retardant material, wherein said flame retardant material is a product of thermal conversion, before compounding into the thermoplastic polymer, of one or more compounds of formula (I) into a different chemical species having greater thermal stability than the one or more compounds of formula (I) as determined by differential scanning calorimetry or weight loss data obtained while increasing temperatures during thermal analysis, which product is obtained by a process comprising heating in the absence of other components at temperatures of higher than 200° C. from about 0.01 hour to about 20 hours one or more than one compound of formula (I) wherein R is C M is a metal, y is a number of from 1 to 4 so that M
