Beschreibung
Zusammenfassung:	The process consists in incorporating a polyester polythiol derived from an aliphatic polyacid, containing from 2 to 5 carboxylic groups and at least 15 carbon atoms in its molecule, especially a polyester polythiol corresponding to the formula shown, where R, R' and R'' denote [R'-CH=CH-R''-COO-R-SH]n it being possible for the hydrocarbon chains to carry double bonds and/or substituents, and n is above all equal to 2 or 3. In addition, R may denote a single bond, R, a hydrogen atom. The incorporation of the polyester polythiol is carried out simply by mixing or else by reaction of the aliphatic polyacid with sulphur in a hydrocarbon fraction of the asphalt type.
