| abstract |
Disclosed are self-assembling block copolymers including diblock copolymers of the formula (I): n nwherein R 1 is —(CHR—CH 2 —O) p —R′, p=2-6, R is H or methyl, and R′ is H, C 1 -C 6 alkyl, or C 3 -C 11 cycloalkyl, R 2 is C 1 -C 22 alkyl or C 3 -C 11 cycloalkyl, one of R 3 and R 4 is C 6 -C 14 aryl and the other is C 1 -C 22 alkoxy, n and m are independently 2 to about 2000, and 0<x≦n and 0<y≦m, which find use in preparing self-assembled structure and porous membranes. Embodiments of the self-assembled structure contain the block copolymer in a cylindrical morphology. Also disclosed is a method of preparing such copolymers. |
