Title:
THERMOPLASTIC RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/199851
Kind Code:
A1
Abstract:
The resent invention provides a thermoplastic resin composition which achieves low dielectric characteristics that have not been achieved by conventional liquid crystal polymer resin compositions, while maintaining excellent heat resistance and flame retardancy of liquid crystal polymers, and which also has good formability. This thermoplastic resin composition is able to be used for information and communication devices that are used in a high frequency range. A thermoplastic resin composition which contains a liquid crystal polymer (A) and a modified polyolefin (B) having a polar group, wherein the liquid crystal polymer (A) contains a first liquid crystal polymer (a-1) that has a melting point of less than 300°C and a second liquid crystal polymer (a-2) that has a melting point of 300°C or more. It is preferable for the thermoplastic resin composition that the phase structure is a sea-island structure or a bicontinuous structure, and the second liquid crystal polymer (a-2) is contained in at least a sea phase or a continuous phase.
