    Abstract: Block copolymer production involves converting a 1,3-butadien-1-yl terminated polymer P1 with a cationic polymer P2. The polymer P1 has general formula (I), which is produced by splitting of hydrogen halide of a compound having the general formula (II). The compound having general formula (II), is produced from a polymer having general formula (III) with a 1,3-butadiene having general formula (IV). The polymer P2 has general formula (V). The compounds having general formulae (I-V), are new. In formula (I), Pm1 : polymer residue; n : 1-6; Q : H or alkyl; R : alkyl or aryl; and R1>,R2>, R3>,R4>,R5>H or alkyl. In formula (II), Pm1,n, Q, R, R1>, R2>, R3>, R4>, R5>same as variable groups in formula (I); and X : halogen, alkoxy, acyloxy. In formula (III),Pm1,R,Q,X=same as variable groups in formula (I). In formula (IV),R1>,R2>,R3>,R4>,R5>=same as variable groups in formula (I). Provided that: (1) Pm1 is polyisobutenyl residue, and Q and R are methyl. In formula (V), Pm2 : polymeric residue, preferably polystyrene residue and polyisobutenyl residue; Q' : H or alkyl; R' : alkyl or aryl; and Y : halogen, alkoxy or acyloxy.
