THERMOPLASTIC RESIN COMPOSITION AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition which has a thermoplastic resin phase dispersed with a plate crystal having a high aspect ratio; and an effective manufacturing method of the same.SOLUTION: The manufacturing method of a thermoplastic resin composition comprises: a first step for solid-phase mixing one powder comprising a lamellar compound such as montmorillonite and mica with another powder comprising a thermoplastic resin such as an olefin-based resin, at a temperature of the softening point of the thermoplastic resin or below and at a shear speed of 20-400 sec; and a second step for melting to blend the solid-phase mixture thus obtained, wherein the plate crystal dispersed in the phase of the thermoplastic resin has an aspect ratio of 5-100 and a thickness of 1-100 nm.
