Abstract:
The invention relates to a ready-to-use hot melt adhesive containing at least 95% of one or more polyolefin copolymer waxes, which have been prepared by means of metallocene catalysts, characterised in that the polyolefin copolymer wax consists of propylene and one or more further monomers selected from ethylene and branched or unbranched 1-alkenes having 4 to 20 C-atoms and the content of structural units derived from propylene in the copolymer waxes amounts to 80 to 99.9% by weight, and the hot melt adhesive has a surface tension of the melt, measured at a temperature of 170° C., of at most 23 mN/m.

Claim (Index 11):
A hotmelt as a ready-to-use hotmelt adhesive for coating the reverse of sheetlike structures, wherein the ready-to-use hotmelt adhesive comprises at least 95 wt % of one or more polyolefin copolymer waxes produced using metallocene catalysts,\n wherein the polyolefin copolymer wax consists of propylene and one or more further monomers selected from the group consisting of ethylene and branched or unbranched 1-alkenes having 4 to 20 carbon atoms and comprises units of propylene and ethylene, and where the amount of structural units originating from the propylene in the copolymer wax is between 85 and 95 wt %, wherein the polyolefin copolymer wax has a number-average molar mass M n  in the range of 15,000 and 25,000 g/mol and a weight-average molar mass M w  in the range of 25,000 and 35,000 g/mol, a dropping point or ring and ball softening point in the range of 100 and 120\u00b0 C., a heat of fusion of not more than 60 J/g, a melt viscosity, measured at a temperature of 170\u00b0 C., of 8,000 to 15,000 mPa\u00b7s, and a glass transition temperature of not more than \u221215\u00b0 C., and wherein the hotmelt adhesive has a melt surface tension, measured at a temperature of 170\u00b0 C., of not more than 23 mN/m, wherein the hotmelt adhesive has an entropy-elastic temperature range \u0394T entropy-el (tan \u03b4), measured as the difference from glass transition temperature Tg (tan \u03b4 max ) from loss factor and softening temperature (onset of the loss modulus tan \u03b4 onset ) of 80 to 110\u00b0 C.
