| Abstract: | Functional diblock copolymers possessing central isoprene groups were synthesized by anionic addition in a three-stage process using styrene, isoprene, and 2-vinylpyridine monomers. These diblock copolymers formed microphase-separated structure in the solid state. Where the central isoprene groups are organized regularly at the domain interface of the microphase-separated structure, this is due to the functional groups being located at the block junction position. Addition-condensation of diblock copolymer film with sulfur monochloride formed AnBn star block copolymers by organization effects. © 1993 John Wiley & Sons, Inc. |
