Title:
GRAFT COPOLYMER-CONTAINING SOLID PRODUCT AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/105682
Kind Code:
A1
Abstract:
[Problem] 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 various functional groups introduced only to the surface thereof. [Solution] 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). Requirement (I): 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 absorbance (Abs) satisfies: X<0.01; Y<0.01; and Z≥0.01, where X, Y, and Z represent the values of Abs (key band of the polymer (B)) / Abs(key band of the polymer (A)) at the center (x), the middle point (y), and the point (z), respectively.
