| titleOfInvention | Block (co)polymer, block copolymer composition for asphalt modification, process for producing the same, and asphalt composition |
| abstract | A composition for asphalt modification which comprises (a) a block (co)polymer represented by general formula (I); (S-B)m-S'n (in formula (I), S and S' are each a polymer block mainly composed of an aromatic vinyl compound, B is a polymer block mainly composed of a conjugated diene, and m and n are each an integer of 0 or 1, provided that m+n is 1 or more), wherein the total combined aromatic vinyl compound content in the block (co) polymer is from more than 10% by weight to 100% by weight, and (b) a block copolymer represented by general formula (II) ; S-B-S, general formula (III); S-B-S' and/or general formula (IV) ; (S-B)2-X (in formulas (II) to (IV), S, S' and B have the same meanings as given in general formula (I), and X is a residue of a coupling agent), at a block copolymer (a) /block copolymer (b) ratio (weight ratio) of 10-40/90-60; and further, an asphalt composition in which this composition for modification is added to asphalt. There are provided the composition for asphalt modification excellent in solubility in asphalt, excellent in storage stability at high temperatures, further low in melt viscosity and excellent in asphalt characteristics, and the asphalt composition available for road pavement or waterproof sheets. |
