Abstract:
1. A poly(arylene ether)-poly(hydroxy ether) block copolymer comprising: at least one poly(hydroxy ether) block having the structure: wherein A is a residue of structure 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 11 -R 14 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 8 to R 10 are each independently hydrogen, or C 1 -C 12 hydrocarbyl; and wherein n is about 1 to about 60; and at least one poly(arylene ether) block; wherein the mole ratio of poly(hydroxy ether) blocks to poly(arylene ether) blocks is 0.95:1 to 1.00:1.
