TOUGHNESS MODIFIER FOR CURABLE RESIN, AND CURABLE RESIN COMPOSITION

摘要

A toughness modifier for a curable resin having excellent toughness-modifying effects and good dispersibility with respect to a curable resin containing a thermoplastic resin, as well as good dispersibility in a cured product of a curable resin composition; and a curable resin composition containing the toughness modifier for a curable resin. A toughness modifier for a curable resin (D) obtained by emulsion-polymerizing 5-50 mass% of a vinyl monomer (B) in the presence of 50-95 mass% (as rubber polymer components) of a rubber-like polymer (A) latex using 0.5-15 parts by mass (with respect to 100 parts by mass of (A) and (B)) of a nonionic reactive surfactant (C).
