Sulfur foam product and process |
| abstract |
A process for producing a sulfur foam which comprises forming a sulfur system containing an aliphatic polysulfide and optionally molten elemental sulfur, contacting and reacting an acid with the sulfur system to obtain a sulfur system-acid adduct, said acid being capable of forming CO 2 or COS upon reaction with an isocyanate or isothiocyanate; and reacting polyisocyanate with the adduct to obtain sulfur foam. n Preferably the acids used in the preparation of the sulfur foam are carboxylic acids. The preferred aliphatic polysulfides include the liquid polysulfides derived by the reaction of sodium polysulfide with dichloroethyl ether and dichloroethyl formal. |
