Title:
HOLLOW PARTICLE, METHOD FOR PRODUCING HOLLOW PARTICLE, RESIN COMPOSITION, AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2023/074651
Kind Code:
A1
Abstract:
Provided are: a hollow particle which exhibits good dielectric properties and solvent resistance and which can lower the dielectric constant and dielectric loss tangent of a resin molded body; and a method for producing the hollow particle. The hollow particle comprises a shell that contains a resin and a hollow part that is surrounded by the shell and which has a porosity of 50% or more. The shell contains a polymer containing 70 mass% or more of crosslinkable hydrocarbon monomer units as the resin. In a hollow particle immersion test, when adding 0.1 mg of hollow particles to 4 mL of toluene in an environment at 25°C, shaking the same for 10 minutes at a shaking speed of 100 rpm and then leaving to rest for 48 hours, the amount of hollow particles that sediment in the toluene is less than 5 mass%.
