  • Thiol polyesters
    Patent number: 4126482
    Abstract: New polythiols-polyesters and corresponding polysulphides in the --SH group wherein sulphur is contained in the alcohol residue after the formation of esters. These polyesters are derived from aliphatic polyacids, saturated or not, wherein the molecule contains a minimum of 15 atoms of carbon. They are formulated by the action of a mercapto-alcanol on the corresponding polyacid, in a liquid which gives an azeotropic mixture with water. These products are useful as additives to asphalts, bituminous products, coatings, mastics and cements.

  • Sulfur emulsion in bituminous material
    Patent number: 3970468
    Abstract: Process for dispersing molten sulphur in a hydrocarbon material, such as asphalt, tar and more particularly bitumen. The dispersion is effected in such a way as to produce an emulsion of sulphur in very fine particles, with dimensions not exceeding 10 microns, in the hydrocarbon material. A turbine with a gap or clearance of about 0.1 to 2.25 mm. is very useful for this purpose. The emulsions obtained are particularly suitable for road surfaces.
