Abstract: The present invention discloses a polymer particle with hollow structure which consists of an inner void and a shell region containing acrylate-type copolymer, wherein the shell region is polymerized by an acrylate monomer having a double bond (monomer) with an acrylate monomer having at least two double bonds (crosslinker). The present invention also discloses a method for forming the provided polymer particle with hollow structure, wherein this method employs a diluent which is a good solvent for the monomer and the crosslinker, but poor solvent for the preparing acrylate-type copolymer, so as to form the shell region.
