Title:
SOLID COMPOSITION AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/075149
Kind Code:
A1
Abstract:
A solid composition according to the present invention contains a propylene-based polymer B and a polymer A, and satisfies the following requirements (1)-(3). Requirement (1): The propylene-based polymer B forms a continuous phase, and the polymer A forms a dispersed phase. Requirement (2): The glass transition temperature (Tg) of the polymer A is less than 0°C. Requirement (3): The degree of crystal orientation of the solid composition represented by the following formula is 60-80%. Formula (1): degree of crystal orientation (%)={(180-hw040)/180}×100 [In formula (1), hw040 is a half-value width (degree) of the maximum peak in a distribution curve of an azimuth angle for the scattering intensity of the (040) plane of the α-form of the propylene-based polymer, obtained from a two-dimensional wide-angle X-ray scattering image of a central part of the solid composition.]
