ABSTRACT:
A method for securing splices in uncured rubber articles prior to vulcanization and secured splices resulting therefrom. The method includes covering a splice and two ends of uncured rubber with syndiotactic 1,2-polybutadiene, adhering the syndiotactic 1,2-polybutadiene to the uncured rubber adjacent to the splice, and curing the rubber. The rubber compound to which the syndiotactic 1,2-polybutadiene is adhered does not have to contain syndiotactic 1,2-polybutadiene. In addition, because the syndiotactic 1,2-polybutadiene is preferably melted into the rubber compound, there are no uniformity problems caused by the additional layer over the splice.
