Patent

CA 2234762

A composition that includes an olefinic-terminated polyalkadiene that includes carboxy ester linking groups and at least one nascent secondary hydroxyl group that is capped with a monoisocyanate. The composition also includes a free radical-polymerizable monomer such as an olefinic monomer and, optionally, a second polymeric material. In a preferred embodiment the composition is an adhesive that also includes a phosphorus-containing compound and an ambient temperature-active redox catalyst system.

La présente invention concerne une composition incluant un polyalcadiène à terminaison oléfine contenant des groupes carboxy de liaison ester et au moins un groupe hydroxyle secondaire à l'état naissant coiffé par un monoisocyanate. La composition inclut également un monomère à polymérisation radiculaire tel qu'un monomère oléfine et, éventuellement, une seconde matière polymère. Dans une réalisation préférée, la composition est un adhésif incluant un composé contenant du phosphore et un système catalyseur d'oxydoréduction actif à température ambiante.
