Title:
STYRENE-BASED RESIN COMPOSITION, FLAME RETARDANT STYRENE-BASED RESIN COMPOSITION, MOLDED BODY, AND PATCH ANTENNA
Document Type and Number:
WIPO Patent Application WO/2021/167096
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a styrene-based resin molded body which exhibits an excellent dielectric constant, dielectric loss tangent and color tone, and which undergoes little decrease in characteristics due to the usage environment. The present invention is a styrene-based resin composition which contains a styrene-based resin (A1) having a styrene-based monomer unit as a repeating unit, and which is characterized in that: the amount of a catechol derivative contained in the styrene-based resin (A1) is 6 µg or less per 1 g of the styrene-based resin (A1); the total amount of a dimer of the styrene-based monomer unit and a trimer of the styrene-based monomer unit is 5000 µg or less per 1 g of the styrene-based resin (A1); and the composition has a dielectric constant of 3 or less and a dielectric loss tangent of 0.02 or less.
