| 摘要 |
A method for adhering a polybutadiene formed article, which comprises (1) a step of subjecting the polybutadiene formed article to an ozone treatment, an electron ray treatment, a corona discharge treatment, a plasma discharge treatment, an ultraviolet ray laser treatment or a chemical treatment, to thereby reduce the water contact angle of the surface of said formed article, and (2) a step of adhering the resultant polybutadiene formed article being reduced in its water contact angle to a polar resin formed article. The method allows the improvement of the joining (adhesion) force between a polybutadiene formed article and a polar resin formed article, and allows the further improvement of the joining force by the additional use (combination) of a solvent for those formed articles. |
