Blends of poly(aryl ether) resins and polyetherimide resins

Claim 1

A molding composition comprising a blend of from about 95 to about 5 weight percent of a poly(aryl ether) and from about 5 to about 95 weight percent of a polyetherimide of the following formulae: ##STR29## wherein a is an integer greater than 1, to about 10,000 or more, --O--R 4 --O-- is attached to the 3 or 4 and 3' and 4' positions and R 4 is selected from (a) a substituted or unsubstituted aromatic radical such as ##STR30## (b) a divalent radical of the formula: ##STR31## wherein R 6 is independently C 1 to C 6 alkyl, or halogen and R 7 is selected from --O--, ##STR32## 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 5 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 ##STR33## wherein R 6 and R 7 are as previously defined and R 7 may be a direct bond; ##STR34## wherein --O--Z< is a member selected from ##STR35## wherein R 8 is independently hydrogen, lower alkyl or lower alkoxy ##STR36## wherein the oxygen may be attached to either ring and located ortho or para to one of the bonds to the anhydride carbonyl group wherein a, R 4 and R 5 are as previously defined.
