Patent ID: 8481650

Claim:
A method for producing a polymer comprising: (i) a step of subjecting an anionic polymerizable monomer to a living anionic polymerization in the presence of an anionic polymerization initiator; and (ii) a step of adding a cinnamyl alcohol or a derivative thereof represented by the following formula [I] to a reaction system for attaching the cinnamyl alcohol or a derivative thereof at a growth end wherein R 1 represents an alkyl group or alkoxy group; m represents an integer of 0 to 5 and when m is 2 or more, R 1 s may be the same or different; R 5 represents a hydrogen atom, alkali metal atom, trialkylsilyl group or a substituent represented by the following formula [II] wherein R 3 represents a hydrogen atom or a C1-C6 alkyl group; and R 4 represents an alkyl group which may be substituted by an alkoxy group, a cycloalkyl group which may be substituted by an alkoxy group, a phenyl group which may be substituted by an alkyl group, or a phenyl group which may be substituted by an alkoxy group.
