(57) [Problem] To provide a hydroxystyrene-based polymer having a high syndiotactic structure. SOLUTION: The following general formula (1): (Wherein, m is an integer of 1-3.) The number average molecular weight having a structural unit represented by is 600 or more polymers, and 30% in the racemic pentad by the tacticity is 13 C-NMR hydroxystyrene-based polymers in which syndiotactic structure above, and as catalyst (a) represented by the following general formula (2) and / or formula (3) MR 2 a R 3 b R 4 c X 1 4- (a + b + c) (2) and MR 2 d R 3 e X 1 3- (d + e) (3 a transition metal compound represented by), the reaction product of at least one cocatalyst main catalyst component The following general formula (4) was used: By polymerizing a substituted styrene monomer represented by the following formula, the compound has the following general formula (5) having a high syndiotactic structure: Producing a substituted styrene-based polymer represented by the following formula, followed by contacting this with an acid or a base in the presence of an organic solvent to carry out a deprotection grouping reaction, thereby producing the hydroxystyrene-based polymer.
