Beschreibung
Zusammenfassung:A composition comprising a polyarylate-siloxane copolymer, said copolymer comprising arylate structural units having Formula (I); wherein R1 and R2 are independently at each occurrence a halogen atom, a nitro group, a C1-C20 aliphatic radical, a C3-C20 cycloaliphatic radical, or a C3-C20 aromatic radical; "b" and "c" are independently integers from 0 to 4; and at least one organosiloxane structural unit, wherein said polyarylate-siloxane copolymer is free of organic carbonate linkages.
