Manufacturing method of macromonomer, macromonomer, method for producing graft copolymer using the same, polymer composition and molded article

摘要

Problem to be solved: to provide a macromonomer having a high yield at high yield without producing a polymerization inhibitor and a macromonomer having good polymerization with itself and other monomer.Solution: in the presence of an organic alkali metal compound, one or more monomer anions selected from the group consisting of conjugated dienes and aromatic vinyl compounds is polymerized to produce an active end polymer (1) and an active terminal polymer obtained in step (1) in the presence of polar compounds A method for producing a macromonomer comprising a process (2) for reacting a compound represented by formula (I).(in Formula 1, R1 to R5 each independently represent hydrogen atoms, and alkyl groups of 1 to 5 carbon atoms)No selection
