Title:
THERMOPLASTIC ELASTOMER COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2022/186053
Kind Code:
A1
Abstract:
One aspect of the present invention is a thermoplastic elastomer composition comprising: 100 parts by mass of (A) a block copolymer or a hydrogenated product thereof, the block copolymer containing a polymer block (X) mainly including a vinyl aromatic compound, and a polymer block (Y) mainly including a conjugated diene compound; 1 to 400 parts by mass of (B) an ethylene·α-olefin copolymer that satisfies the following requirements (b-1) to (b-3); and 0 to 200 parts by mass of (C) a polyolefin resin that satisfies the following requirement (c-1). (b-1) The kinematic viscosity at 100°C is 5 to 5,000 mm2/s and the kinematic viscosity at 40°C is 50 to 100,000 mm2/s. (b-2) The weight average molecular weight (Mw) determined by gel permeation chromatography (GPC) is 1,000 to 30,000. (b-3) The content ratio of an ethylene structural unit is 15 to 85 mol%. (c-1) MFR (230°C, 2.16 kg) is 0.1 to 500 g/10 min.
