  • Hydrocarbon resins, processes for their manufacture and adhesive compositions containing such resins
    Patent number: 5571867
    Abstract: The invention relates to a hydrogenated hydrocarbon resin of a softening point from 75.degree. to 110.degree. C. having an Mw/Mn of less than 2 as determined by GPC, an aromaticity level of from 15 to 25%, and a melt viscosity in mPa.s at a shear rate of 50 sec.sup.-1 of less than 500 mPa.s, preferably less than 300 mPa.s at 160 .degree. C.
    Type: Grant
    Filed: January 9, 1995
    Date of Patent: November 5, 1996

  • Petroleum resins and their production
    Patent number: 4994516
    Abstract: Hot melt adhesives comprising ethylene/vinyl acetate copolymer, wax, and a resin containing 5 to 80 wt. % of units derived from olefinically unsaturated aromatic compounds, 5 to 80 wt. % of units derived from C.sub.5 or C.sub.6 olefines or diolefines or a mixture thereof, and from 7 to 45% of units derived from a terpene. The hot melt adhesive composition has improved color and compatibility over ethylene/vinyl acetate copolymer and wax blends containing resins of significant portions of cyclopentadiene or dicyclopentadiene. The hot melt adhesive of the invention also show improved adhesive properties on substrate such as glass and aluminum.
