To improve the joining (adhesion) force of a polybutadiene formed article and a polar resin formed article, and to further improve the joining force by selecting (combining) a solvent(s) for these formed articles. n A method for adhering a polybutadiene formed article, which comprises (1) the step of reducing the water contact angle of a surface of the polybutadiene formed article by ozone treatment, electron beam treatment, corona discharge treatment, plasma discharge treatment, ultraviolet laser treatment or chemical treatment, and (2) the step of adhering the polybutadiene formed article reduced in the water contact angle to a polar resin formed article. |
