A novel styrene copolymer comprising a styrene repeating unit (a) represented by the general formula: (See Formula I) (wherein R1 is a hydrogen atom or a hydrocarbon group having not more than 20 carbon atoms; n is an integer of 1 to 3 and when n is 2 or 3, R1s may be the same or different) and olefin repeating unit (b) represented by the general formula: (See Formula II) (wherein R2 is a hydrogen atom or a saturated hydrocarbon group having not more than 20 carbon atoms) or diene repeating unit, which contains 0.1 to 99.9 wt% of said olefin repeating unit (b) or diene repeating unit (c) wherein intrinsic viscosity measured in 1,2,4-trichlorobenzene at 135°C is 0.07 to 20 dl/g and the stereoregularity of the styrene repeating unit chain is a high degree of syndiotactic configuration. This styrene copolymer is excellent in heat resistance and chemical resistance, and further it can be infection molded at low temperature, and has good compatibility with other reline and the like.
