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.
Claims19
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 58 wt % to 82 wt % of a bio curable resin, and 18 wt % to 42 wt % of an epoxy resin, based on a total weight of the curable resin,
- the graft copolymer is a core-shell type graft copolymer comprising a core containing a rubbery polymer and a shell formed by graft polymerizing a graft monomer to the rubbery polymer, and
- the shell has a weight average molecular weight of 10,000 g/mol to 85,000 g/mol.
