Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
A composition suitable for molding, comprising a crystalline polyamide polymer and a poly(etherimide) polymer of the following formulae (I) or (II): wherein a is an integer greater than 1, ―O―R 1 ―O― is attached to the 3 or 4 and 3' or 4' positions and R 1 is selected from (a) a substituted or unsubstituted aromatic radical of the formula: (b) a divalent radical of the formula: wherein R 3 is independently C, to C 6 alkyl, or halogen and R 4 is selected from -0-, -S-, -SO-, ―SO 2 ― alkylene of 1 to 6 carbon atoms, cycloalkylene of 4 to 8 carbon atoms, alkylidene of 1 to 6 carbon atoms or cycloalkylidene of 4 to 8 carbon atoms, R 2 is selected from an aromatic hydrocarbon radical having from 6-20 carbon atoms and halogenated derivatives thereof, or alkyl substituted derivatives thereof, wherein the alkyl group contains 1 to 6 carbon atoms, alkylene and cycloalkylene radicals having from 2 to 20 carbon atoms, C 2 ―C 8 alkylene terminated polydiorganosiloxane and a divalent radical of the formula wherein R 3 are as previously defined; wherein -O-Z is a member selected from wherein R 6 is independently hydrogen, lower alkyl or lower alkoxy wherein R, and R 2 and a are as defined above.
Claim 2
Dependent Claim
214 words
A composition suitable for molding, comprising a crystalline polyamide polymer and a poly(etherimide) polymer of the following formulae (I) or (II): wherein a is an integer greater than 1, ―O―R 1 ―O― is attached to the 3 or 4 and 3' or 4' positions and R 1 is selected from (a) a substituted or unsubstituted aromatic radical of the formula: (b) a divalent radical of the formula: wherein R 3 is independently C, to C 6 alkyl, or halogen and R 4 is selected from -0-, -S-, -SO-, ―SO 2 ― alkylene of 1 to 6 carbon atoms, cycloalkylene of 4 to 8 carbon atoms, alkylidene of 1 to 6 carbon atoms or cycloalkylidene of 4 to 8 carbon atoms, R 2 is selected from an aromatic hydrocarbon radical having from 6-20 carbon atoms and halogenated derivatives thereof, or alkyl substituted derivatives thereof, wherein the alkyl group contains 1 to 6 carbon atoms, alkylene and cycloalkylene radicals having from 2 to 20 carbon atoms, C 2 ―C 8 alkylene terminated polydiorganosiloxane and a divalent radical of the formula wherein R 3 are as previously defined; wherein -O-Z is a member selected from wherein R 6 is independently hydrogen, lower alkyl or lower alkoxy wherein R, and R 2 and a are as defined above.
