Abstract
The present invention relates to flame retardant polymer compositions which comprise mixtures of phosphinic acid salts and dihydro-oxa-phospho-phenantrene derivatives. The compositions are especially useful for the manufacture of flame retardant compounds based on polycondensates like polyesters, polyamides and polycarbonates.
