摘要：
Disclosed are terminal-modified difunctional sulfur-containing polymers that are the reaction products of a sulfur-containing diol, an aldehyde or a ketone, and a compound containing a functional group. Compositions comprising the terminal-modified difunctional sulfur-containing polymers useful as sealants are also disclosed.
