BLOCK COPOLYMER COMPOSITION

摘要

A thermally stabilized block copolymer composition comprising: a block copolymer which comprises at least one polymer block derived mainly from a monoalkenyl aromatic compound and at least one polymer block derived mainly from a conjugated diene compound and in which the content of units derived from the monoalkenyl aromatic compound is 5 to 95 wt.% based on the block copolymer; and phenolic stabilizers. Due to the incorporation of the two or more specific phenolic stabilizers in the block copolymer of a monoalkenyl aromatic compound and a conjugated diene compound, the block copolymer composition has excellent thermal stability even at high temperatures, is highly inhibited from generating a gel, and has an excellent color tone.
