Abstract:
1. A compound produced from the reaction between a) di(hydroxyethyl)polysulfides, homopolymers of di(hydroxyethyl)polysulfides, or a mixture of di(hydroxyethyl)polysulfides and homopolomyers of di(hydroxyethyl) polysulfides; and b) mono-basic or di-basic carbonic acids, their anhydrides, mixtures of dibasic carbonic acids and their anhydrides, or mixtures of mono-basic carbonic acids and their anhydrides wherein said carbonic acids and their anhydrides are selected from the group consisting of C wherein the molar ratio of the components is between 1:1 and 2:1, wherein said reaction is conducted at a temperature of between about 80° C. and about 130° C., and wherein said reaction is conducted in the presence of a protonic acidic catalyst.
