Abstract: The present invention addresses the problem of providing a cross-copolymer having excellent flexibility, heat resistance, cold resistance and mechanical properties. The present invention also addresses the problem of providing a resin composition which is prepared using the cross-copolymer, has excellent compatibility with polyolefin resins and aromatic resins, and has excellent flexibility, heat resistance and cold resistance.The problem can be solved by a cross-copolymer produced by a polymerization process comprising a coordination polymerization step and a crossing step, wherein the coordination polymerization step comprises copolymerizing an ethylene monomer, a specific olefin monomer and an aromatic polyene together using a single site coordination polymerization catalyst to synthesize an ethylene-olefin-aromatic polyene copolymer that meets a specific requirement, and the crossing step comprises carrying out a polymerization in the co-presence of the ethylene-olefin-aromatic polyene copolymer and an aromatic vinyl compound monomer using an anionic polymerization initiator or a radical polymerization initiator.
