Title:
THERMOPLASTIC RESIN COMPOSITION, HOT MELT ADHESIVE, AUTOMOBILE MEMBER, AND HYGIENIC MATERIAL MEMBER
Document Type and Number:
WIPO Patent Application WO/2019/026891
Kind Code:
A1
Abstract:
A thermoplastic resin composition containing an olefinic polymer (a) and a hydrogenated block copolymer (b), wherein the heat of crystal fusion (∆H) measured at a heating rate of 10°C/minute in differential scanning calorimetry in the olefinic polymer (a) is less than 80 J/g, the hydrogenated block copolymer (b) is a hydrogenation product of a block copolymer comprising a polymer block (A) having structural units derived from an aromatic vinyl compound as the main component thereof and a polymer block (B) having structural units derived from a conjugated diene compound as the main component thereof, the content of the polymer block (A) in the hydrogenated block copolymer (b) is 1-60% by mass, the content of the hydrogenated block copolymer (b) in the thermoplastic resin composition is 1-30 parts by mass with respect to a total of 100 parts by mass of the olefinic polymer (a) and the hydrogenated block copolymer (b), and the olefinic polymer (a) and the polymer block (B) of the hydrogenated block copolymer (b) are compatible on a molecular level.
