FLAME RETARDANT POLYMER COMPRISING PHOSPHORUS-CONTAINING REPEATING UNITS, PLASTIC COMPOSITION COMPRISING THE FLAME RETARDANT POLYMER, PROCESS FOR PRODUCING THE FLAME RETARDANT POLYMER AND USE THEREOF

摘要

The present invention relates to a flame retardant polymer comprising phosphorus-containing repeating units of general formula A_n‐X‐B_m, wherein A is a polymeric radical, B is a phosphorus-containing moiety according to a general formula and X is an n + m-valent phosphorus-containing group. The present invention further relates to a plastic composition comprising the flame retardant polymer, to a process for producing the flame retardant polymer and to the use thereof.
