Abstract:
Blends containing polycarbonate and/or polyester carbonate and from 0.1 to 30 parts by weight of phosphonate amine of formula (I)A3âˆ’yNâ€”Byâ€ƒâ€ƒ(I) in whichA represents a radical of formula (IIa) R1 and R2 are each independently of the other unsubstituted or substituted C1-C10-alkyl or unsubstituted or substituted C6-C10-aryl, R3 and R4 are each independently of the other unsubstituted or substituted C1-C10-alkyl or unsubstituted or substituted C6-C10-aryl, or R3 and R4 together represent unsubstituted or substituted C3-C10-alkylene, y represents the numerical values 0, 1 or 2, and substituents B are each independently hydrogen, optionally halogenated C2-C8-alkyl, unsubstituted or substituted C6-C10-aryl, and from 0.1 to 20 parts by weight of at least one phosphorus compound of the general formulae (IIa), (IIb), (IIc) and (IId) whereinR1, R2, R3 and R4 are each independently of the others optionally halogenated C1- to C8-alkyl, or C5- to C6-cycloalkyl, C6- to C20-aryl or C7- to C12-aralkyl each optionally substituted by alkyl and/or by halogen, the substituents n are each independently of the others 0 or 1, k represents from 0 to 30, and X represents a mono- or poly-nuclear aromatic radical having from 6 to 30 carbon atoms, whereinR5 and R6 are each independently of the other optionally halogenated C1-C24-alkyl, or C5-C6-cycloalkyl, C6-C20-aryl or C7-C12-aralkyl each optionally substituted by halogen and/or by C1-C10-alkyl, or R5 and R6 in the case of formula (IId) form an alkyl chain, Me represents a metal selected from main groups 1 to 3 and subsidiary groups VIII, 1B and 2B of the periodic system, and q is determined by the valency of the metal ion, and, optionally, impact strength modifiers, the indicated amounts being based on the total mixture.
