| titleOfInvention | Block copolymer hydride and extended film composed thereof |
| abstract | The present invention provides a hydrogenated block copolymer and a stretched film composed of the hydrogenated block copolymer, wherein the hydrogenated block copolymer is composed of a repeating unit [I] derived from an aromatic vinyl compound as a main component. Two polymer blocks [A], and one polymer block with the repeating unit [I] derived from an aromatic vinyl compound and the repeating unit [II] derived from a chain conjugated diene compound as main components The block copolymer [C] composed of the segment [B] is a hydrogenated block copolymer. The weight fraction of the polymer block [A] in the block copolymer [C] is set to wA. When the weight ratio of block [B] to block copolymer [C] is set to wB, the ratio of wA to wB (wA: wB) is 45:55 to 65:35, and repeating unit [I] When the weight fraction of the segment [B] is set to w [I B ] and the weight fraction of the repeating unit [II] to the polymer block [B] is set to w [II B ], w [I B ] and w [ The ratio of II B ] (w [I B ]: w [II B ]) is 40: 60 ~ 55: 45, more than 90% of the total unsaturated bonds of the block copolymer [C] are hydrogenated, and the weight average molecular weight is 60,000 to 150,000, a glass transition temperature based on dynamic viscoelasticity of the low temperature side [Tg 1] is 0 ℃ Glass transition temperature on the high temperature side and [Tg 2] less than 135 ℃. According to the present invention, it is possible to provide a novel block copolymer hydride having improved heat resistance, and an stretched film composed of the block copolymer hydride having improved heat resistance to changes in retardation. |
