Title:
BLOCK COPOLYMER HYDROGENATE, RESIN COMPOSITION, AND APPLICATIONS THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/103047
Kind Code:
A1
Abstract:
Provided is a block copolymer hydrogenate having a polymer block (A) that contains more than 70 mol% structural unit derived from an aromatic vinyl compound and a polymer block (B) that contains at least 30 mol% structural unit derived from a conjugated diene compound, wherein the block copolymer hydrogenate further satisfies the following conditions. Condition (1): the content of the polymer block (A) in the block copolymer hydrogenate is 1 to 30 mass%. Condition (2): the conjugated diene compound comprises isoprene. Condition (3): the total content of the 1,2-bond unit and 3,4-bond unit in the structural unit derived from the conjugated diene compound is at least 60 mol%. Condition (4): the hydrogenation ratio of the polymer block (B) is at least 60 mol%. Condition (5): a sequential temperature region is present in which tan δ, as measured according to JIS K 7244-10 (2005) using conditions of a strain of 0.1%, a frequency of 1 Hz, a measurement temperature of -70 to 100°C, and a rate of temperature increase of 3°C/minute, is at least 1.0 and the maximum width of this temperature region is at least 16°C.
