Abstract
The present invention relates to flame retardant polymer compositions which comprise melamine phenylphosphonates and mixtures with dihydro-oxa-phosphaphenanthrene derivatives. The compositions are especially useful for the manufacture of flame retardant compounds based on polyfunctional epoxides or polycondensates like polyesters, polyamides and polycarbonates.
