A styrenic copolymer having at least one structural unit represented by general formula (I) and either a structural unit represented by general formula (II) or a structural unit represented by general formula (IX), the content of the unit (II) or the unit (IX) being 0.01 to 99.9 mole %. In these formulae each symbol is as defined in the specification. This copolymer is highly syndiotactic in the stereoregularity of the chain composed of the structural units (I) and is excellent in the adhesion and compatibility with other resins.
