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.
