Document Type and Number:

WIPO Patent Application WO/2019/230527

Kind Code:

A1

Abstract:

Provided are: a modified hydrogenated product of a block copolymer having a polymer block (A) containing a structural unit derived from an aromatic vinyl compound and a polymer block (B) containing a structural unit derived from a conjugated diene compound, wherein the modified hydrogenated product has one or more functional groups selected from among alkoxysilyl groups, carboxyl groups, amino groups, hydroxy groups, epoxy groups, and acid anhydride-derived groups, and satisfies the requirements below; a method for producing the modified hydrogenated product; and a resin composition containing the modified hydrogenated product. Requirement (1): The rate of weight change after being left alone for 30 minutes at 330°C in a nitrogen atmosphere is at least -5.5%. Requirement (2): The peak top intensity of tan δ is at least 1.0 as measured at a temperature of -70 to 120°C under the conditions of a strain of 0.1%, a frequency of 1 Hz, and a heating rate of 3°C/min in accordance with JIS K7244-10 (2015).
