CORE-SHELL TYPE POLYMER FOR INTERLAYER FILM, RESIN COMPOSITION AND INTERLAYER FILM FOR LAMINATED GLASS

摘要

A core-shell type polymer, which comprises core particles and a shell at least partly coating the surface of the core particles and satisfies the following relationship: X_SA_S≥75 [wherein: X_S represents the content (mass%) of an acetone-soluble matter relative to the total mass of the core-shell type polymer; and A_S represents the acid value (mmol/g) of the acetone-soluble matter], and a resin composition comprising the core-shell type polymer provide an interlayer film for a laminated glass, said interlayer film having excellent adhesiveness to a glass, preferably, excellent adhesiveness to a glass, high transparency and good self-standing property.
