Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
95 words
A composition comprising an admixture of a) a semi-crystalline, thermoplastic poly(arylene ether ketone) having a crystalline melting point above about 320°C and b) a substantially non-crystalline fluorocarbon polymer capable of withstanding temperature above about 320°C for at least about 5 minutes without substantial degradation, said fluorocarbon polymer comprising a copolymer of tetrafluoroethylene wherein the tetrafluoroethylene content of the copolymer is about 5 to about 85% by weight based on the weight of the copolymer, said composition being capable of being melt processed at a temperature above the crystalline melting point of the poly(arylene ether ketone).
Claim 2
Dependent Claim
95 words
A composition comprising an admixture of a) a semi-crystalline, thermoplastic poly(arylene ether ketone) having a crystalline melting point above about 320°C and b) a substantially non-crystalline fluorocarbon polymer capable of withstanding temperature above about 320°C for at least about 5 minutes without substantial degradation, said fluorocarbon polymer comprising a copolymer of tetrafluoroethylene wherein the tetrafluoroethylene content of the copolymer is about 5 to about 85% by weight based on the weight of the copolymer, said composition being capable of being melt processed at a temperature above the crystalline melting point of the poly(arylene ether ketone).
