The cationic polymerization of 1,Zbutylene oxide initiated by radical catalysts has been investigated in detail in the presence of maleic anhydride. The active species of this ionic polymerization was thought to be a conjugated radical of poly(maleic anhydride).
Poly(methylmethacrylate)-poly(4-vinylpyridine) diblock copolymers were synthesized by sequential anionic polymerization, l,l-diphenyl-3-methylpentyllithium was used as initiator and LiCI was added to the system as ligand to modify both initiator and active chain end in order to avoid side reactions.
