Title:
COMPOSITION AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2022025680
Kind Code:
A
Abstract:
To provide a composition having excellent tensile characteristics, impact resistance and dispersibility.SOLUTION: A composition contains 50-90 wt.% of a polypropylene-based resin (A), 5-25 wt.% of an olefinic resin (B) and 5-25 wt.% of an aromatic vinyl-based resin (C), and has a continuous phase a composed of the polypropylene-based resin, a dispersion phase b that is dispersed in the continuous phase a and contains the olefinic resin, and a dispersion phase c composed of the aromatic vinyl-based resin, in which the dispersion phase c exists in the continuous phase a, the dispersion phase c exists in the dispersion phase b or the dispersion phase c exists on an interface between the continuous phase a and the dispersion phase b, and in a resin phase-separation structure observed by a transmission electron microscope, an average circle-equivalent diameter of the dispersion phase c is 50 nm or more and 1 μm or less and an average distance between centers of gravity of the dispersion phase c is 300 nm or more and 1,500 nm or less.SELECTED DRAWING: Figure 2
