Abstract
The moisture vapor transmission rates of sealants containing liquid polysulfides made from mixtures of a hexylene dihalide and a chloroethyl formal wherein the molar ratio is from about 1.5:1 to about 2.3:1 are extremely low. A preferred ratio is 0.64:0.36. The new liquid polysulfide is useful in conventional sealant formulations for insulated glass window units.
