摘要： This invention relates to a highly tacky pressure sensitive adhesive having superior high temperature properties. The adhesive is formed of about 50-100 parts of a diblock copolymer and about 0-50 parts of a linear or radial triblock copolymer, a tackifier and a curing agent. The adhesive thus formed can be coated on a backing to form a tape and then vulcanized in situ to provide a precured or prevulcanized adhesive tape having high temperature properties and superior tack properties.

摘要： A normally nontacky but potentially tacky adhesive lift-off tape which comprises an adhesive film composition which normally exhibits a plastic nontacky state but is convertible to an elastomeric tacky state by the application of substantial stress, i.e., stretching sufficiently or striking with typewriter type, as well as the process of applying the said adhesive film. This film composition consists essentially of thermoplastic and elastomeric A-B block copolymers wherein the A-blocks are thermoplastic and the B-blocks are elastomeric and about 20-120 parts per one hundred parts by weight of the block copolymers of certain normally solid resins adapted to associate principally with the thermoplastic A-blocks of said copolymers. In these copolymers the A-blocks are derived from styrene or styrene homologues and the B-blocks are derived from conjugated dienes or lower alkenes. The normally solid resins preferably are selected from the group consisting of alpha-methylstyrene-vinyl toluene copolymers and coumarone-indene copolymers.

摘要： A thermoplastic hot melt pressure-sensitive adhesive composition which is resistant to heat deterioration at elevated temperatures and, therefore, may be melted and maintained hot and ready for coating for extended periods of time without detracting from the properties of the adhesive. The composition is based upon a linear or radial A-B-A block copolymer and a mixture of solid and liquid tackifier resins and contains a heat stabilizing component which comprises an oil-soluble, heat-reactive phenol formaldehyde resin and a suitable antioxidant which preferably consists predominantly of a metal dithiocarbamate.

Preferably the adhesive is formed of a weight ratio of solid rubber to liquid rubber of about 1:0.5 to about 1:7. These adhesives exhibit improved adhesion in cold weather and oily surface applications and other properties. The pressure sensitive adhesives can be used in health care, industrial and drug delivery systems.
