Abstract

The present invention relates to flame retardant polymer compositions which comprise aminoguanidine phenylphosphinates and mixtures with additional flame retardants. The compositions are especially useful for the manufacture of flame retardant compounds based on polyfunctional epoxides or polycondensates like polyesters, polyamides and polycarbonates.
