PROBLEM TO BE SOLVED: To provide multifunctional sulfur-containing polymers.SOLUTION: There are disclosed multifunctional sulfur-containing polymers that are the reaction products of a sulfur-containing diol, a polyol containing at least three hydroxyl groups per polyol molecule, and an aldehyde, a ketone, or a combination thereof. Sealant compositions comprising the multifunctional sulfur-containing polymers are also disclosed. In a first aspect of the present disclosure, terminal-modified sulfur-containing polymers are provided comprising the reaction products of reactants comprising: (a) a sulfur-containing diol; (b) a polyol containing at least three hydroxyl groups per polyol molecule; and (c) a reactant selected from an aldehyde, a ketone, and a combination thereof.SELECTED DRAWING: None |
