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.

Abstract: Provided is a method for producing carbon nanotibers having excellent conductivity, crystallinity and dispersibility. A method for producing carbon nanofibers, which uses an activated species mainly composed of cobalt as a catalyst, while using carbon monoxide as a carbon source. The catalyst is obtained by having a carrier, which is composed of an oxide having a specific surface area of 0.01-5 m2/g and containing magnesium, support 3-90% by mass of the activated species. By controlling the reaction temperature, the carbon monoxide partial pressure and the gas flow rate of the carbon monoxide, CNF having more excellent conductivity, crystallinity and dispersibility can be produced, thereby obtaining carbon nanofibers having excellent conductivity, crystallinity and dispersibility.
