Title:
THERMOPLASTIC RESIN COMPOSITION, PRODUCTION METHOD THEREFOR, AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2017/169814
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a thermoplastic resin composition that has a novel phase structure capable of exhibiting excellent mechanical strength, for which raw material selection and production management can be conducted across a wide composition range and with a high degree of freedom; a production method; and a molded body. The present invention comprises a polyolefin resin PO, a polyamide resin PA, and a compatibilizer blended therein, has first phases F1 comprising the PA, the compatibilizer, and/or a reaction product thereof, and has a second phase F2 having no PO and being interposed between first phases F1. The first phases F1 comprise: a matrix F11 comprising PA; and a dispersed phase F12 that is dispersed inside the matrix F11 and comprises the compatibilizer and/or a reaction product thereof. The present invention has branch shaped phases having branching sections, as first phases F1. The present invention comprises: a step in which the PA and the compatibilizer are melt-kneaded, having a compatibilizer blending ratio of 11%-45% by mass when the total of the PO, PA, and compatibilizer is 100% by mass; and a step in which an obtained first composition and PO are melt-kneaded.
