Title:
THERMOPLASTIC POLYMER COMPOSITION, AND MOUDLED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/031550
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a thermoplastic polymer composition which is capable of adhering to synthetic resins, ceramics, and metals or the like, without having to perform primer treatment, can be handled as a moulded article, and exhibits flexibility, excellent adhesive properties in a broad temperature range spanning from a low temperature to room temperature, and high thermal creep resistance; and a moulded article using said thermoplastic polymer composition. This thermoplastic polymer composition includes 10-100 parts by mass of a polar-group-containing polypropylene-based resin (B) per 100 parts by mass of a hydrogenated block copolymer (A) obtained by hydrogenating a block copolymer which includes: a polymer block (S) including aromatic vinyl compound units; and a polymer block (D) including conjugated diene compound units. The hydrogenated block copolymer (A) is a mixture which includes: a hydrogenated block copolymer (A1) obtained by hydrogenating a block copolymer which has at least one tanδ maximum value in the range -60 to -40˚C, and which is represented by formula (i), namely (S-D)n, or formula (ii), namely (D-S)n-D (in formulae (i) and (ii), S is a polymer block including aromatic vinyl compound units, D is a polymer block including conjugated diene compound units, and n is an integer in the range of 1-5); and a hydrogenated block copolymer (A2) obtained by hydrogenating a block copolymer represented by formula (iii), namely (S-D)m-S (in formula (iii), S is a polymer block including aromatic vinyl compound units, D is a polymer block including conjugated diene compound units, and m is an integer in the range of 1-5). The mass ratio of the hydrogenated block copolymer (A1) to the hydrogenated block copolymer (A2) is in the range of 20:80 to 99:1.
