Patent ID: 8907042

Claim:
A polymer composition comprising a polyetherimide of the formula wherein n is greater than 1, each R is the same or different, and is selected from an aromatic hydrocarbon group having 6 to 30 carbon atoms, a halogenated derivative thereof, a straight or branched chain alkylene group having 2 to 10 carbon atoms, a cycloalkylene group having 3 to 20 carbon atoms, or a divalent group of the formula wherein Q 1 is selected from —O—, —S—, —C(O)—, —SO 2 —, —SO—, —C y H 2y — wherein y is 1 to 5, and a halogenated derivative thereof, each Z is the same or different and is an aromatic C 6-24 monocyclic or polycyclic moiety optionally substituted with 1 to 6 C 1-8 alkyl groups, 1 to 8 halogen atoms, or a combination thereof, the divalent bonds between the —O—Z—O— group and the phenyl substituents are in the 3,3′, 4,3′, 3,4′ and 4,4′ positions; the divalent bonds of the —O—Z—O— group being made from a bis(halophthalimide) composition comprising, based on the weight of the bis(halophthalimide) composition, from more than 45 to less than 75 weight percent of a 3,3′-bis(halophthalimide) of the formula less than 10 weight percent of a 3,4′-bis(halophthalimide) of the formula and from more than 45 to less than 75 weight percent of a (4,4′-bis(halophthalimide) of the formula wherein each X is independently fluoro, chloro, bromo, or iodo and R is as defined above, and wherein the polyetherimide comprises less than 5 weight percent of a cyclic byproduct, based on the total weight of the polyetherimide.
