A copolymer (I) comprises: (A) an alpha -olefin; (B) a monoalkenylaromatic hydrocarbon; and (C) a diene. Independent claims are included for: (i) a process for the production of (I) by copolymerization of (A), (B) and (C) in the presence of a catalyst prepared from (I) and (II), (I) and (III) or (I), (II) and (III) where (I) is a transition metal complex of formula (1), (2) or (3) (IIi) is an organoaluminum compound of formula (4) (IIii) is a cyclic aluminoxan of formula (5) (IIiii) is a linear aluminoxane of formula (6) (III) is a boron compound of formula (7), (8) or (9); and (ii) a molded article comprising the copolymer (I).
