| abstract |
The present invention provides a joint seal. The joint seal may include three layers. The first and third layers each contain a base polymer grafted with monomers. At least one of the first and third layers is grafted with a monomer and a benzene ring-containing comonomer. The second layer contains a polyolefin polymer. The joint seal has improved adhesion, corrosion resistance, and insulation compared to conventional joint seals. |
