[0014] The red phosphorus may or may not be coated. In a preferred embodiment, the red phosphorus RP1 is uncoated. This simplifies the feasibility of manufacturing.

[0015] According to the present invention, the metal of the metal carbonate MC1 is selected from alkali metals, alkaline earth metals, transition metals, internal transition metals, and / or mixtures thereof. In preferred embodiments, the metal of the metal carbonate MC1 is selected from transition metals, preferably zinc. Thus, the polymer composition is less likely to produce undesirable phosphorus-containing products, and the release of phosphorus-containing compounds is reduced. If the polymer composition further contains copper compound CC1, borate B1, or both, the release of phosphorus-containing compounds is further reduced.

[0016] In preferred embodiments, the metal of the metal carbonate MC1 is selected from lanthanides, actinides, and / or mixtures thereof, preferably lanthanides, more preferably cerium carbonate and / or lanthanum carbonate, and more preferably lanthanum carbonate.

[0018] In preferred embodiments, the metal of the metal carbonate MC1 is selected from alkaline earth metals, preferably magnesium, calcium, strontium, barium, and more preferably calcium. Thus, the polymer composition is less likely to produce undesirable phosphorus-containing products, and the release of phosphorus-containing compounds is reduced. If the polymer composition further contains copper compound CC1, borate B1, or both, the release of phosphorus-containing compounds is further reduced.

[0019] In a preferred embodiment, the oxidation state of the metal in the metal carbonate MC1 is 3 + and / or 4 + Preferably 3 + Therefore, the bulk density increases.

If the polymer composition further contains copper compound CC1, borate B1, or both, the release of phosphorus-containing compounds is further reduced.

[0022] In a preferred embodiment, the metal carbonate MC1 is not sodium carbonate, and preferably not sodium carbonate and / or zinc carbonate. Therefore, the bulk density increases.

[0023] According to the present invention, the polymer composition may contain copper compound CC1.
