Document Type and Number:
WIPO Patent Application WO/2023/112996
Kind Code:
A1
Abstract:
Provided is a modified product of a hydrogenated product of a block copolymer in which a resin composition having an excellent balance of mechanical properties such as tensile strength, tensile strain at break, and impact resistance can be obtained by addition. A modified hydrogenated product of a block copolymer includes a polymer block containing a structural unit derived from an aromatic vinyl compound and a polymer block containing a structural unit derived from a conjugated diene compound, wherein: the conjugated diene compound contains isoprene and a conjugated diene compound other than isoprene; the vinyl bonding amount of the polymer block is at most 30 mol%; and the modified hydrogenated product has one or more functional groups selected from among an alkoxysilyl group, a carboxy group, an amino group, a hydroxy group, an epoxy group, and an acid anhydride-derived group, has a peak top intensity of loss tangent of at most 0.95, and has a melt flow rate (MFR) of at least 0.5 g/10 min.
