The hollow polymer particles of the present invention comprise a shell wall having for a main component thereof a copolymer obtained by polymerizing a monomer group (I) including a radical polymerizable water-soluble monomer (A) and a radical polymerizable water-insoluble monomer (B), and have a thickness of the shell wall of 5 to 80 nm. In addition, in the hollow polymer particle production process of the present invention, a monomer group (I) including a radical polymerizable water-soluble monomer (A) and a radical polymerizable water-insoluble monomer (B) is radical- polymerized using a polymerization initiator in an aqueous medium.
本发明的空心聚合物颗粒包括壳壁,壳壁的主要成分是通过聚合包括可自由基聚合的水溶性单体(A)和可自由基聚合的水不溶性单体(B)的单体基团(I)而得到的共聚物,壳壁的厚度为5至80纳米。此外,在本发明的空心聚合物颗粒生产工艺中,包括可自由基聚合的水溶性单体(A)和可自由基聚合的水不溶性单体(B)的单体基团(I)在水介质中使用聚合引发剂进行自由基聚合。
