ABSTRACT:
An epoxy resin composition which is tough and has excellent heat resistance and adhesion is obtained by dispersing, in an epoxy resin, polymer particles with a glass transition temperature of lower than 20.degree. C. obtained by emulsion polymerization of a (meth)acrylic acid ester monomer by using, as an emulsifier, an end alkyl group-containing polymer with an acid value of greater than 200 or a salt thereof obtained by polymerization of a polymerizable monomer containing an unsaturated carboxylic acid in the presence of an alkyl mercaptan. The epoxy resin composition is useful, for example, as adhesives, molding materials, paints, sealants.
