摘要：The invention as disclosed provides a composition having properties such that it can be used as a substitute for asphalt or portland cement, comprising the sulfur reaction product of (1) elemental sulfur; (2) from 5 to 20 weight percent of the sulphur reaction product of a first hydrocarbon (a) which is polyunsaturated with the unsaturated portions being reactable with elemental sulfur and (b) which by itself when reacted with elemental sulfur forms a gel; and (3) from 5 to 20 weight percent of the sulfur reaction product of a second hydrocarbon (a) which has one or more unsaturated groups reactable with elemental sulfur and (b) which by itself when reacted with sulfur does not form a gel but forms a brittle product; and (c) which when the first and second hydrocarbons are so reacted with sulfur prevents said gel from forming; said sulfur reaction product being formed by causing the aforesaid reactants to undergo an exothermic reaction; said sulfur reaction product having a viscosity curve approximating that of asphalt, a penetration of from - ii 5 to 100, a softening point of from 10.degree.C to 70.degree.C and a ductility of at least 100. The composition is prepared by mixing together elemental sulfur with the above-described first and second hydrocarbons and then heating the reactants to a temperature in the range of 120.degree. to 200.degree.C so as to cause an exothermic reaction to take place between the reactants.
