摘要:
A pressure sensitive adhesive composition is described comprising a polyisobutylene polymer having a first functional group and an acrylic polymer having a second functional group present in the acrylic polymer backbone. The first and second functional groups form a hydrogen bond. In some embodiments, the adhesive composition further comprises a crosslinker that covalently crosslinks the second functional group(s) present in the polymer backbone of the acrylic polymer. Also described are adhesive articles, such as a tape, methods of adhesively bonding, and methods of making a pressure sensitive adhesive.
摘要:
A pressure sensitive adhesive composition is described comprising unfunctionalized (e.g. polyisobutylene) synthetic rubber and an acrylic polymer having functionalized polyisobutylene polymer bonded to the acrylic polymer. In some embodiments, the functionalized polyisobutylene polymer has a first functional group hydrogen bonded with a second functional group present in the acrylic polymer backbone. In other embodiments, the functionalized polyisobutylene polymer is covalently bonded to the acrylic polymer backbone. Also described are adhesive articles, such as a tape, methods of adhesively bonding, and methods of making a pressure sensitive adhesive.

摘要:
Adhesive compositions and articles that contain these adhesive compositions are described. More particularly, the adhesive compositions include (a) a block copolymer prepared from monoethylenically unsaturated monomers and (b) a tackifier mixture. The adhesives compositions can be adhered to many substrates including those having a non-polar surface.

摘要:
Multi-phase blended pressure sensitive adhesives are described. The adhesives include a first phase containing at least one non-halogenated polyisobutylene material and a second phase comprising a thermoplastic elastomer. Exemplary thermoplastic elastomers include polyolefins, styrenic block copolymers, acrylic polymers and silicone polymers. Crosslinked adhesives, including those crosslinked with actinic radiation are also described. Adhesive articles including such adhesives are disclosed as well
