Use of a phosphorus compound of the formula (I) as flame retardant, where the definitions of the symbols in the formula (I) are as follows: 

Flame retardant

The present invention relates to flame retardant polymer compositions which comprise melamine phenylphosphinates 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.

Melamine phenylphosphinate flame retardant compositions

Disclosed is a polymer foam with density in the range from 5 to 120 kg/mcomposed of a polymer component including at least one styrene polymer and from 0.1 to 5 parts by weight of a flame retardant mixture including at least one phosphorus compound of the formula PRRR. A process for producing the polymer is also disclosed.

Halogen-free, phosphorus-containing flame-retardant polymer foams

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.

Melamine phenylphosphonate flame retardant compositions

The present invention relates to flame retardant polymer compositions which comprise combinations of hydroxyalkyl phosphine oxides with 1,3,5-triazine compounds and polyfunctional epoxide compounds. The compositions are in the form of epoxy laminates which are useful for the manufacture of prepregs, laminates for the preparation of printed circuit boards and printed wiring boards.
