Title:
HOLLOW RESIN PARTICLE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2021/085189
Kind Code:
A1
Abstract:
Provided is a hollow resin particle which introduces a hollow region into a resin layer, which enables a reduction in dielectric properties and a reduction in dielectric loss tangent, and in which a hollow portion can be formed easily. Also provided is a method for producing this type of hollow resin particle in a simple manner. A hollow resin particle according to an embodiment of the present invention has a shell part and a hollow portion surrounded by the shell part. The shell part includes an aromatic polymer (P1) obtained by polymerizing a monomer composition containing an aromatic crosslinkable monomer (a), an aromatic monofunctional monomer (b) and a (meth)acrylic ester-based monomer (c) having a specific structure.
