Description

[Technical field]

[0001] The present invention relates to a window module, a vehicle equipped with the same, and a method for producing a thermoplastic elastomer composition. [Background technology]

[0002] A rubber sealant called a weatherstrip is used around the periphery of a vehicle window to prevent water, dust, sound, etc. from entering the vehicle interior. When connecting a vehicle window glass to a vehicle body panel via a weatherstrip, a polyurethane adhesive is generally used. Specifically, an adhesive is applied to the periphery of the window glass and the weatherstrip that holds up the window glass, and the adhesive is then attached to the vehicle body panel and pressed against it to connect the window glass. In order to improve adhesion with the polyurethane adhesive, a primer treatment is applied to the weatherstrip and the periphery of the window glass before the adhesive is applied (see, for example, Patent Document 1).
