FIRE-RETARDANT, IMPACT RESISTANT THERMOPLASTIC MOULDING COMPOSITION Russian patent published in 2012 - IPC C08L69/00 C08L67/02 C08L55/02 C08L33/16 C08K5/521 

FIELD: chemistry.

SUBSTANCE: composition contains the following in %: a) 35-78% aromatic polycarbonate, b) 6-55% thermoplastic polyester - polyethylene terephthalate, c) 5-15% halogenated acrylate, d) 3-15% impact resistance modifier, e) 2-15% phosphate-containing compound and f) 0.05-0.5% fluorinated polyolefin. The acrylate contains repeating structural units of the following formula: in which R₁, R₂, R₃, R₄ and R₅ denote hydrogen, alkyl or aryl, n ranges from 0 to 5, m ranges from 10 to 10000, and R denotes halogen. The phosphate-containing compound is selected from a compound of formula (III) O-P-[-OCH₂C(CH₂Br)₃]₃ (III) and compounds of formula , in which R₁, R₂, R₃ and R₄ denote C₁-C₈-alkyl, C₅-C₆-cycloalkyl, C₆-C₂₀-aryl or C₇-C₁₂-aralkyl, unsubstituted or substituted with alkyl, n equals 0 or 1, N equals 0.1-30, X denotes a mono- or polycyclic aromatic residue with C₆-C₃₀ or a linear or branched aliphatic residue with C₂-C₃₀.

EFFECT: invention enables to obtain a composition with higher impact resistance and fire resistance.
