Claim 6
Dependent Claim
199 words
A composition as defined in claim 1 wherein the polyetherimide has repeating units of the following formula: wherein e is an integer greater than 1, preferably from about 10 to about 10,000 or more, -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 such as or (b) a divalent radical of the formula: wherein R 3 is independently C 1 to C 6 alkyl, aryl or halogen and R 4 is selected from -0-. -S-. -SO 2 -, -so-. 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 to 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 and C 2 to C 8 alkylene terminated polydiorganosiloxane or a divalent radical of the formula wherein R 3 and R 4 are as previously defined.
Claim 7
Dependent Claim
