Abstract
The flameproofed, non-dripping polyalkylene terephthalate molding compounds according to the invention based on phosphoric acid esters may be used for the production of moldings. The fire behavior of the polyalkylene terephthalate molding compounds is improved by the addition of certain phosphoric acid esters, a surprising reduction in the phosphorus content of the molding compounds being achieved at the same time, particularly in combination with highly heat-resistant thermoplastics.
