Patent ID: 8258212

Claim:
A process for the production of a solid intermediate compound that is provided for being incorporated in a liquid bitumen of petroleum origin or in mineral oils for the production of a liquid bitumen/polymer, comprising the steps of: a) preparing a solid bitumen by heating said solid bitumen at a temperature of between 200° and 250 ° C., the solid bitumen having a sufficiently low penetration coefficient at room temperature 25° C. that the penetration coefficient measures zero on a 100 th millimeter scale; b) bringing a polymer to a temperature of between 110° and 190° C.; c) mechanically, vigorously mixing said solid bitumen as prepared according to the step a) with the polymer as prepared according to the step b) to form a mixture; d) cooling the mixture to obtain a solid intermediate compound obtained from said solid bitumen and said polymer; and e) dividing the solid intermediate compound into a divided form.
