Abstract

A pressure-sensitive adhesive composition capable of substantial cohesion without curing comprises, as its basic ingredient, an uncured stereospecific elastomeric polymer of isoprene. Specified polymers are the trans, cis, isotactic, syndrotactic and tritactic. The composition may also contain a tackifier, a compatible anti-oxidant, a metal oxide filler, starch as an adhesive modifier and at least one plasticizer. Specified tackifiers are dehydrogenated rosin, a hydrogenated rosin, mixtures of the two or esters of the same such as the glycerol ester of hydrogenated rosin, and the polyterpenes, while zinc oxide, aluminium oxide and their mixtures are specified fillers, lanolin, hydrogenated polybutene, and white mineral oil are specified plasticizers and ditolylamines in combination with a petroleum wax is the specified antioxidant. Preferred proportions are 25-35% of the isoprene polymer, 14 to 40% resinous tackifier, 10-35% zinc oxide, 5-10% starch, 3-7% plasticizer and 0.1 to 2% antioxidant.ALSO:A pressure-sensitive plaster or tape incorporates a pressure sensitive adhesive composition comprising as its basic ingredient an uncured stereospecific elastomeric polymer of isoprene - it is especially useful as a surgical tape or plaster. Tape backings specified are paper and 80/72 cotton cloth. The compositions may also contain a tackyfier, a reinforcing filler, a compatible anti-oxidant, an adhesive modifier and a plastizer (see Div. C3). In an example a composition of 51 1/2 lbs. of the isoprene polymer, 45 lbs. Rosin, 43 lbs. zinc oxide, 11 lbs. starch, 4 1/2 lbs. polybutene, 2 lbs. lanolin and 1/2 lb. of an antioxidant are callender rolled on to 80/72 cotton cloth, the composition being at 225 DEG F.
