Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 26 words
A blend of thermoplastic resins comprising: (i) at least one resin selected from the group consisting of polycarbonate, poly(ester-carbonate) and polyarylate; and (ii) amorphous polyamide resin.
Claim 2
Dependent Claim 26 words
A blend of thermoplastic resins comprising: (i) at least one resin selected from the group consisting of polycarbonate, poly(ester-carbonate) and polyarylate; and (ii) amorphous polyamide resin.
Claim 3
Dependent Claim 13 words
The blend of Claim 1 wherein said at least one resin is polycarbonate.
Claim 4
Dependent Claim 13 words
The blend of Claim 1 wherein said at least one resin is poly(ester-carbonate).
Claim 5
Dependent Claim 13 words
The blend of Claim 1 wherein said at least one resin is polyarylate.
Claim 6
Dependent Claim 27 words
The blend of Claim 1 which contains a weight ratio of from about 49/1 to about 1/49 amorphous polyamide to total polycarbonate, poly(ester carbonate) and/or polyarylate content.
Claim 7
Dependent Claim 16 words
The blend of Claim 5 wherein said ration is about 9/1 to about 1 to 9.
Claim 8
Independent Claim 49 words
A method for preparing a thermoplastic blend comprising the steps: (i) melt blending thermoplastic resins comprising polyamide and at least one resin selected from the group consisting of polycarbonate, poly(ester-carbonate), and polyarylate; and (ii) cooling the resultant resin melt at a sufficient rate to produce an amorphous polyamide phase.
Claim 9
Independent Claim 49 words
A method for preparing a thermoplastic blend comprising the steps: (i) melt blending thermoplastic resins comprising polyamide and at least one resin selected from the group consisting of polycarbonate, poly(ester-carbonate), and polyarylate; and (ii) cooling the resultant resin melt at a sufficient rate to produce an amorphous polyamide phase.
