Abstract:
An object of the present invention is to provide a cross-copolymer having excellent softness and heat resistance which is useful as a thermoplastic elastomer, and provide a method for producing thereof. The present invention provides a method for producing a cross-copolymer comprising a coordination polymerization step and an anionic polymerization step, the cross-copolymer has a specific structure. The present invention also provides a cross-copolymer having excellent moldability, softness and heat resistance, which can be produced under the producing conditions satisfying that the molecular weight distribution of the copolymer obtained in the coordination polymerization step is in a specific range.

Claim (Index 6):
A cross-copolymer comprising an ethylene-aromatic vinyl compound-aromatic polyene copolymer chain and an aromatic vinyl compound polymer chain, wherein\n the ethylene-aromatic vinyl compound-aromatic polyene copolymer chain and the aromatic vinyl compound polymer chain bonded via the aromatic polyene unit, and the cross-copolymer satisfies all the following features (1) to (3): (1) in the ethylene-aromatic vinyl compound-aromatic polyene copolymer macromonomer, the aromatic vinyl compound unit content is 15 mol % or more and 30 mol % or less, the aromatic polyene unit content is 0.01 mol % or more and 0.2 mol % or less, and the rest is the ethylene unit content; (2) a weight average molecular weight (Mw) of the ethylene-aromatic vinyl compound-aromatic polyene copolymer macromonomer is 100000 or more and 250000 or less and a molecular weight distribution (Mw/Mn) is 3.5 or more and 6 or less; (3) a mass ratio of the ethylene-aromatic vinyl compound-aromatic polyene copolymer macromonomer component in the cross-copolymer obtained through the anionic polymerization step is 60% by mass or more and 95% by mass or less.
