Abstract: This invention relates to pressure sensitive adhesive formulations which include a saturated midblock thermoplastic elastomer such as a block copolymer of polystyrene and hydrogenated polydiene such as Kraton.RTM. G and a fully saturated tackifying resin derived from petroleum feedstock polymerized in the presence of aluminum chloride and having a Mn ranging from 400 to 800, a softening point of 40.degree. to 70.degree. C. and a glass transition temperature less than 45.degree. C. whereby the adhesive formulations have a rolling ball tack of less than 10 cm., a 180.degree. peel of from 1 to 4 pounds per inch, a 90.degree. quick stick of from 0.5 to 2.0 pounds per inch and a Polyken probe tack of higher than 400 g/cm.sup.2 with a formulation containing 100 to 180 phr of the saturated tackifying resin.

Abstract: This invention relates to an improved process for preparing linear olefins and waxes, particularly linear olefin waxes. More particularly, this invention relates to an improved process for polymerizing ethylene to obtain linear olefins and waxes having a number average molecular weight (M.sub.n) ranging from about 500 to 5000.The process can be generally described as a two-stage process wherein the first stage is an ethylene oligomerization followed by a second stage metathesis.Still more particularly, this invention relates to an improved process for polymerizing ethylene to obtain a product comprising at least 70 weight percent linear olefin waxes.
