    摘要: Disclosed is a new styrenic copolymer comprising: (a) repeating styrene units of general formula (I), wherein R1 represents a hydrogen or halogen atom, or a hydrocarbon group having 20 or less carbon atoms and n is an integer of 1 to 3, provided that R1 groups may be the same or different from each other when n is 2 or 3, and (b) repeating olefin units of general formula (II), wherein R2 represents a hydrogen atom or a saturated hydrocarbon group having 20 or less carbon atoms, or (c) repeating diene units, wherein the proportion of the repeating olefin units (b) or diene units (c) is 0.1 to 99.9 % by weight. The copolymer has a limiting viscosity of 0.07 to 20 dl/g as measured in 1,2,4-trichlorobenzene at 135°C and the stereoregularity of the chain of the repeating styrene units is highly syndiotactic. It is excellent in the resistance to heat, chemicals and so forth and capable of low-temperature injection molding. It has also a good compatibility with other resins.
