| This invention relates to a novel pressure sensitive adhesive formed of a liquid and solid rubber which is substantially resin free. 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. | ||||||

| The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by using as the adhesive an interpolymer comprising a conjugated diene and a heterocyclic nitrogen base and containing about 5-180 parts of silica filler per 100 parts by weight of interpolymer. Further improvement is achieved by using a rubber containing about 0.025 to about 1.0 parts by weight of a cobalt compound, calculated as cobalt metal, per 100 parts of rubber. | ||||||

| 233 | Lamp basing cement | US32053173 | 1973-01-02 | US3876559A | 1975-04-08 | JAFFE MARY S |
| A basing cement for an electric lamp is disclosed which is of the dual-purpose type for bonding electrical inleads to the base in the lamp. The adhesive binder comprises the heat-cured product of a 1,2-butadiene prepolymer, a vinyl type crosslinker and a freeradical initiator. A particulate filler is also included in the cement which determines if the heat-cured product will be insulative or electrically-conductive. Either type cement can be heat-cured during high speed lamp manufacture to form the solid adhesive from a liquid suspension of the polymerization reactants which does not contain volatile solvents.

| An adhesive composition comprises a butadiene-methyl isopropenyl ketone copolymer and a cellulose derivative, the latter being present generally in an amount of 25-75 per cent of the weight of the polymer present. The polymer preferably contains 60-80 per cent butadiene and 40-20 per cent methyl isopropenyl ketone. The cellulose derivative may be either an ester such as the acetate or nitrate, or an ether such as benzyl cellulose. Volatile solvents such as methyl ethyl ketone, butanol, or ethyl acetate, fillers such as carbon black, calcium silicate, silica, or zinc oxide, curing agents such as sulphur, vulcanization accelerators such as xanthates or dithiocarbamates, and resins such as phenol-formaldehyde resins, chlorinated rubber, lime-hardened rosin, zinc resinate, or polyvinyl resins, may be incorporated. In one example, stearic acid and mercaptobenzthiazole are also added. Specifications 804,201 and 804,203 are referred to. | ||||||
