Abstract: Production of 1,1-difluoroalkyl amines (I) comprises reacting a carboxamide (II) with oxalyl fluoride or difluorophosgene. Production of 1,1-difluoroalkyl amines of formula (I) comprises reacting a carboxamide of formula (II) with oxalyl fluoride or difluorophosgene: R1 = H, R, (AO)nR, 3-14C aryl, 4-15C aralkyl or NR4R5; R = 1-12C alkyl; A = 2-12C alkylene; n = 1-5; R4, R5 = 1-8C alkyl or NR4R5 is a 4- to 7-membered ring with 3-16 C atoms; R2, R3 = R, 3-14C aryl or 4-15C aralkyl or NR2R3 is a ring with 3-16 C atoms; alternatively R1 forms a 3-16C ring with R2 and/or R3.

Abstract: A flame resistant poly(ester)carbonate composition is disclosed. The composition contains at least one phosphorus-silicon compound, the compound has a phosphorus content of 1 to 20% and a silicon content of 1 to 20%, and is characterized in that its weight loss (assessed by thermogravimetric analysis under nitrogen inert gas at a heating rate of 20° K/min,) at 280° C. is less than 30%. The preferred phosphorus-silicon compound is produced by thermal oligomerization from phosphorylated silanes.

Abstract: Phosphorylated organosiloxanes are used as flame retardants or flame retardant synergists in plastics. Phosphorylated organosiloxanes are used as flame retardants or flame retardant synergists in plastics. The phosphorylated organosiloxanes are preferably reaction products of phosphorus compounds of formula R1O-P(=O)R2-OR1 (I) and halosilanes of formula (R3)n-SiX4-n (II). n = 0-3 (preferably 1-3); X = halogen, preferably Cl or Br; R1 = alkyl; R2 = H, alkyl, aryl, alkoxy or aryloxy; and R3 = alkyl or aryl.
