| titleOfInvention | Wax coating compositions |
| abstract | A wax composition comprises from 0.1 to 50 per cent by weight of an oxidized polyethylene with an oxygen content of between 0.1 per cent and 10 per cent by weight of the polymer, and from 99.9 to 50 per cent by weight of petroleum wax. Polyethylene having a specific viscosity prior to oxidation of from 0.05 to 0.75 as determined from 0.4 gram of the polymer in solution in 100 mol. of methyl cyclohexane, and preferably of a highly branched-type prepared by polymerizing at pressures above 1000 atmospheres at about 140 DEG C. in the presence of cyclohexane, is oxidized by bubbling air or oxygen mixtures thereof through the molten polymer at 100 DEG to 250 DEG C., or by blowing oxygen over solid polythylene shavings or films less than about 2 mls. thick at about 90 DEG C. The wax may be paraffin, preferably of m.p. 50 DEG to 60 DEG C. or microcrystalline of m.p. 60 DEG to 82 DEG C., and may contain up to 0.5 per cent mineral oil. The compositions may be prepared by dissolving the polyethylene in molten wax, preferably at between 70 DEG to 175 DEG C., with stirring and slow cooling. The compositions have a lower solution temperature and cloud point and greater tensile strength and ductility than petroleum wax alone and may be applied as coatings for paper, cloth or fabric, from a hot molten bath without separation of the wax. |
