GRAFT COPOLYMER-CONTAINING SOLID PRODUCT AND USE THEREOF

The issue of the invention is to provide a core-shell type graft copolymer which substantially retains the physical properties and shape of a raw material polymer, and has a high proportion of variousfunctional groups introduced only to the surface thereof. This core-shell type polymer solid product...

Beschreibung
Zusammenfassung:	The issue of the invention is to provide a core-shell type graft copolymer which substantially retains the physical properties and shape of a raw material polymer, and has a high proportion of variousfunctional groups introduced only to the surface thereof. This core-shell type polymer solid product contains a graft copolymer (C) having a main chain portion derived from a precursor polymer (A) and a graft portion derived from a polymer (B), wherein a core portion (a) of the solid product contains the main chain portion derived from (A), a shell portion (b) of the solid product contains the graft portion derived from (B), and the solid product satisfies requirement (I) that is when infrared absorption spectroscopic measurement is performed on cross-sections passing through the center (x) of the solid product, a point (z) on the surface of the solid product where the distance between the center (x) and the surface is shortest, and a middle point (y) of a line connecting the center (x) and the point (z), the abs
