    • Described is a method for producing a void-containing resin molded product which enables producing a void-containing resin molded product having a high color saturation and an appearance excellent in brightness and heat insulation properties by stretching polymer-molded product containing a single crystalline polymer, and a void-containing resin molded product obtained by the production method. A first aspect of the method for producing a void-containing resin molded product is a method for producing a void-containing resin molded product, the method including: stretching a polymer-molded product containing a single crystalline polymer in at least one axial direction, wherein a yield stress (A) and a stress (L30) at an elongation of 30% in a stress-strain curve of the polymer-molded product in the stretching in the one axial direction satisfy Relationship (I): L30/A
    • 描述了一种通过拉伸含有单晶聚合物的聚合物模制产品来制造含空隙的树脂模制产品的方法,该方法能够制备具有高色饱和度和亮度和隔热性能优异外观的含空隙的树脂模塑制品, 以及通过该制造方法得到的含空隙的树脂成形品。 含空隙的树脂成型体的制造方法的第一方面是含空隙的树脂成形体的制造方法,其特征在于,在至少一个轴向上拉伸含有单晶聚合物的聚合物成型体, 其中,在一个轴向的拉伸中,聚合物成型体的应力 - 应变曲线的伸长率为30%时的屈服应力(A)和应力(L30)满足关系式(I):L30 / A <0.90 关系(一)
