Abstract
A vulcanized rubber composition containing at least 30% by weight, based on the amount of the rubber component, of syndiotactic-1,2-polybutadiene has a high adhesion, and can be easily and firmly adhered to another vulcanized rubber composition or to a porous material through a syndiotactic-1,2-polybutadiene thin film by a hot-melt adhesion process.
Claims2
A hot-melt adhesion process for vulcanized rubber, comprising hot pressing a first member consisting of a vulcanized rubber composition, whose rubber component contains at least 30% by weight of syndiotactic-1,2-polybutadiene, to a second member comprising a rubber composition defined as the first member or a porous material, such as cloth, paper, leather or wood in the presence of a hot-melt adhesive consisting of a syndiotactic-1,2-polybutadiene thin film interposed between the members.
