Abstract

Provided are a curable resin composition, which reduces environmental pollution by using an eco-friendly bio-based epoxy resin instead of the conventional petroleum-based epoxy resin, satisfies all the mechanical strength characteristics required by a curable resin composition containing the conventional petroleum-based epoxy resin, and has excellent productivity and excellent mechanical properties by dispersing a graft copolymer in a curable resin through a powder phase dispersion method, and an adhesive composition comprising the same.

Dependent claims

A curable resin composition comprising a continuous phase containing a curable resin, and a dispersion phase containing a graft copolymer,

wherein the curable resin comprises a bio curable resin and an epoxy resin, and
a peak area ratio for the bio curable resin and the epoxy resin (bio curable resin:
epoxy resin) is 0.60 to 5.60:1, the peak area ratio being obtained by dissolving 0.2 g of the curable resin composition in acetone, adding 40 mL of methanol thereto, filtering a supernatant through a 2 mL vial for liquid chromatography using a polytetrafluoroethylene filter of 0.22 μm, and detecting in accordance with an elution time by an evaporation light scattering detector (ELSD) using high performance liquid chromatography (HPLC).
