ABSTRACT:
A pressure sensitive adhesive composition which exhibits excellent adhesive strength and holding characteristics within a wide temperature range from ultra-low temperature to high temperature without causing environmental problems is disclosed. The pressure sensitive adhesive composition comprises a random copolymer of isobutylene and paramethylstyrene, and a tackifier, wherein said random copolymer contains 1 to 20% by weight of said paramethylstyrene and has a cross-linked structure. The adhesive composition is particularly useful in forming weather-strip tapes.
