Claims24
A thermoplastic molding composition, which after molding is transparent, said composition comprising
- (a) a polyalkylene terephthalate;
- (b) a bisphenol-A polycarbonate;
- and
- (c) an aromatic polyester carbonate,
- wherein the total amount of component (a) exceeds about 10 to 12 percent by weight of the total composition.
A thermoplastic molding composition which after molding is transparent, which comprises
- (a) from 90 to 15 percent by weight of a bisphenol-A polycarbonate;
- (b) from 10 to 85 percent by weight of a polyalkylene terephthalate;
- and
- (c) from 5 to 50 percent by weight of an aromatic polyester carbonate.
A method for producing a transparent molded article which comprises preparing (a) a polyalkylene terephthalate in admixture with (b) a bisphenol-A polycarbonate, wherein the total amount of the polyester component (a) exceeds about 10 to 12 percent by weight of the total composition, adding to said mixture an amount of (c) an aromatic polyester carbonate and subjecting the total composition to a molding operation.
A thermoplastic molding composition, which after molding is transparent, said composition consisting essentially of
- (a) a polyalkylene terephthalate;
- (b) a bisphenol-A polycarbonate;
- and
- (c) an aromatic polyester carbonate, wherein the total amount of component (a) exceeds about 10 to 12 percent by weight of the total composition.
A thermoplastic molding composition, which after molding is transparent, consisting essentially of
- (a) from 90 to 15 percent by weight of a bisphenol-A polycarbonate;
- (b) from 10 to 85 percent by weight of a polyalkylene terephthalate;
- and
- (c) from 5 to 50 percent by weight of an aromatic polyester carbonate.
