A pressure-sensitive adhesive material made of a weakly elastic mixture comprising a continuous phase formed essentially from a physically cross- linked solid rubber, which comprises a blend of A-B-A block copolymer, such as a styrene-isoprene-styrene block copolymer and a diblock copolymer such as styrene-butadiene, styrene-isoprene or a hydrogenated styrene-diene copolymer such as styrene/etyhlene butylene, a compatible tackifying resin and a low- molecular weight polyisobutylene, optionally modified by butyl rubber, and a discontinuous phase comprising one or more hydrocolloids that are soluble and/or swellable in water.
L'invention porte sur un adhésif autocollant consistant en un mélange faiblement élastique comprenant: (a) une phase continue essentiellement formée d'un caoutchouc à l'état solide physiquement réticulé consistant en un mélange d'un copolymère bloc A-B-A, (par exemple du type styrène-isoprène-styrène), d'un copolymère à deux blocs (par exemple un styrène-butadiène, un styrène-isoprène, ou un copolymère hydrogéné de styrène-diène par exemple un styrène/éthylène butylène), d'une résine collante compatible, et d'un polyisobutylène facultativement modifié par un caoutchouc butyle; et (b) une phase discontinue comprenant un ou plusieurs hydrocolloïdes solubles et/ou gonflant dans l'eau.
