Title:
BLOCK-COPOLYMER-CONTAINING RESIN COMPOSITION AND MOLDED ARTICLE THEREOF
Document Type and Number:
WIPO Patent Application WO/2016/047762
Kind Code:
A1
Abstract:
[Problem] To provide a resin composition containing a block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene, with which it is possible to obtain a molded article such as a sheet or film having exceptional impact resistance. [Solution] A resin composition containing a block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene, the resin composition satisfying (A)-(E) below. (A) The conjugated diene content is 22 mass%-35 mass%. (B) The block ratio of vinyl aromatic hydrocarbon is 98-100%. (C) Mw/Mn obtained by GPC is 1.3-3.5. (D) The area ratio of polymer components is 30-55% of the whole in a chromatogram obtained by GPC. (E) The loss tangent obtained by a dynamic viscoelasticity measurement has a single maximum value in a temperature range from -100 to -60°C, and the tan δ value when the temperature is 30°C higher than the temperature of the maximum value is 0.6 or higher relative to tan δ value at the temperature of the maximum value.
