Adhesive resin composition and bonding method
The present invention relates to an inexpensive adhesive resin composition which is applicable even to a base material having a poor bonding property. The adhesive resin composition comprises (A) a polymer having no radical-polymerizable double bond and (B) a radical generating agent in which the radical generating agent (B) is present in an amount of 0.1 to 10 parts by weight on the basis of 100 parts by weight of the polymer (A). In the preferred embodiment of the present invention, the adhesive resin composition further comprises (C) a radical-polymerizable monomer wherein the monomer (C) is present in an amount of 0.1 to 10 parts by weight on the basis of 100 parts by weight of the polymer (A). The radical-polymerizable monomer (C) is a glycidyl group-containing monomer, and the glycidyl group-containing monomer is 4-hydroxybutyl acrylate glycidyl ether.
1. A bonding method comprising:
a step of applying an adhesive resin composition comprising onto a base material, which adhesive resin composition consists of (A) a polymer having no radical-polymerizable double bond, (B) a radical generating agent, and (C) a glycidyl group-containing monomer, and
a step of generating a radical derived from a radical generating agent (B), wherein
the radical generating agent (B) is present in an amount of 0.1 to 10 parts by weight on the basis of 100 parts by weight of the polymer (A), and
the glycidyl group-containing monomer is 4-hydroxybutyl acrylate glycidyl ether and is present in an amount of 0.1 to 10 parts by weight on the basis of 100 parts by weight of the polymer (A) and
a combination of polymer (A)/base material is selected from the group consisting of an epoxy resin/a polyamide, an acrylic resin/a polycarbonate, a polyether-urethane resin/a polyamide, and a polyether-urethane resin/a polypropylene.
