Title:
A thermoplastic resin composition, a forming object, and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6235693
Kind Code:
B2
Abstract:
A thermoplastic resin composition comprising:
a block copolymer (a) having 60 to 80% by mass of a vinyl aromatic monomer unit and 40 to 20% by mass of a conjugated diene monomer unit; and
a copolymer (b) having 60 to 90% by mass of a vinyl aromatic monomer unit and 40 to 10% by mass of an unsaturated nitrile monomer unit, wherein
the block copolymer (a) has at least one polymer block (S) primarily having a vinyl aromatic monomer unit,
the block copolymer (a) has at least one tan ´ peak of dynamic viscoelasticity at a temperature in a range of -73 to -10°C, and
a mass ratio (a)/(b) of the block copolymer (a) to the copolymer (b) is 1/99 to 80/20.
