Patent ID: 6861139

Claim:
A pressure sensitive adhesive weather-strip tape comprising: (a) a substrate having two opposing surfaces; and comprising a foam polymer selected from the group consisting of acrylic foam, urethana foam, and polyethylene foam; and (b) a pressure sensitive adhesive composition bonded to a surface of said substrate, said adhesive composition comprising: (i) a random copolymer of isobutylene and paramethylstyrene, wherein said random copolymer contains 1 to 20% by eight of the paramethylstyrene and has a crosslinked structure, (ii) a tackifier, and (iii) an amine crosslinking agent, capable of performing cross-linking by utilizing brominated sites in the paramethylstyrene, wherein said adhesive composition contains 50 to 150 parts by weight f said tackifier based on 100 parts by weight of said copolymer and is substantially solvent free, the combination of substrate and pressure sensitive adhesive being useful as a weather-strip.
