ABSTRACT:
A producing method of fractionated wax products characterized in that it comprises the steps of preparing as a raw material, solid wax, more particularly, low molecular weight polyolefine wax which is a byproduct when manufacturing polyolefine polymer and which is formed into flakes or pellets whose areas in contact with a solvent are large, bringing the raw material into contact with the solvent for dissolving the raw wax at temperatures lower than a melting point thereof, while increasing the temperature by degrees, and separating a solution containing extracted wax from the raw wax at each temperature so as to remove the solvent from the solution. The resulting wax products have a melting peak point within a range of 40.degree. C. to 130.degree. C., crystal melting heat of 100J/g or more, and a range of melting points of 40.degree. C. to 5.degree. C., when measured by the DSC.
