Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
93 words
A polymer composition comprising: (a) a poly(arylene sulfide) resin present in an amount of about 10 to 90 weight percent based on the total weight of the polymer composition; (b) a poly(amide-imide) resin present in an amount of 10 to 40 weight percent based on the total weight of the polymer composition; and (c) at least one resin selected from the group consisting of a poly(aryl ketone) resin and a poly(aryl sulfone) resin present in an amount of about 5 to 80 weight percent based on the total weight of the polymer composition.
Claim 2
Dependent Claim
93 words
A polymer composition comprising: (a) a poly(arylene sulfide) resin present in an amount of about 10 to 90 weight percent based on the total weight of the polymer composition; (b) a poly(amide-imide) resin present in an amount of 10 to 40 weight percent based on the total weight of the polymer composition; and (c) at least one resin selected from the group consisting of a poly(aryl ketone) resin and a poly(aryl sulfone) resin present in an amount of about 5 to 80 weight percent based on the total weight of the polymer composition.
Claim 3
Dependent Claim
13 words
The composition of claim 1, wherein said (c) is a said poly(aryl ketone).
