    摘要： To provide a resin composition containing a block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene, from which a formed product such as a sheet or a film, having excellent transparency and impact resistance, can be obtained.A resin composition containing a block copolymer of a vinyl aromatic hydrocarbon and a conjugated diene, which satisfies the following (A) to (D): (A) the content ratio (mass) of the conjugated diene is from 22 to 32%, (B) the block ratio of the vinyl aromatic hydrocarbon is from 90 to 98%, (C) Mw/Mn (wherein Mw is the weight average molecular weight and Mn is the number average molecular weight) is from 1.1 to 1.6 obtained by GPC by differential refractive index method, (D) the loss tangent (tan δ) obtained by dynamic viscoelasticity measurement has one local maximum value (tan δ (max)) within a temperature range of from −90 to −30° C., and tan δ (tan δ (max+30° C.)) at a temperature higher by 30° C. than the temperature at the local maximum value (tan δ peak temperature) is at least 0.6 relative to tan δ (tan δ (max)) at the temperature at the local maximum value.

    摘要： Provided is a foamed product having excellent cold insulting effect as a heat insulating material or the like for cold insulation of a cold insulation container. The foamed product 1 includes a paper pellet of 50.0 to 70.0% by mass, a polypropylene resin group of 22.0 to 34.0% by mass, a low density polyethylene resin of 3.0 to 20.0% by mass, and a compatibilizing agent of 0.6 to 2.0% by mass of the polypropylene resin and the polyethylene resin. The paper pellet is formed by mixing fine paper powder of 30.0 to 50.0% by mass having a particle diameter of 30 to 200 μm and hydrophilic macromolecule of 50.0 to 70.0% by mass. The polypropylene resin group is composed of foamable polypropylene resin of 5.0 to 11.0% by mass and other polypropylene resin of 17 to 23% by mass.
