Patent ID: 8865823

Claim:
A poly(phenylene ether)-poly(hydroxy ether)-poly(phenylene ether) triblock copolymer, wherein each poly(phenylene ether) block independently has the structure wherein m is 5 to 50; each occurrence of Z 1 is independently halogen, unsubstituted or substituted C 1 -C 12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C 1 -C 12 hydrocarbylthio, C 1 -C 12 hydrocarbyloxy, or C 2 -C 12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms; and each occurrence of Z 2 is independently hydrogen, halogen, unsubstituted or substituted C 1 -C 12 hydrocarbyl provided that the hydrocarbyl group is not tertiary hydrocarbyl, C 1 -C 12 hydrocarbylthio, C 1 -C 12 hydrocarbyloxy, or C 2 -C 12 halohydrocarbyloxy wherein at least two carbon atoms separate the halogen and oxygen atoms; and wherein the poly(hydroxy ether) block has the structure —B-[A-B] n — wherein A is a residue of structure —O-[G 1 ] t -[E] s -[G 1 ] u -O— wherein each G 1 is independently at each occurrence a C 6 -C 20 aromatic radical, and E is independently at each occurrence a direct bond, or a structure selected from the group consisting of wherein each occurrence of R 4 -R 7 is independently hydrogen or C 1 -C 12 hydrocarbyl, s is 0 or 1, and t and u are each independently 1 to 10; and wherein B is a residue of structure wherein R 1 to R 3 are each independently hydrogen, or C 1 -C 12 hydrocarbyl; and wherein n is 2 to 60.
