Polythioether polymers, sealants containing polythioether polymers, and compounds useful as stabilizing monomers in the manufacture of polythioether polymers are provided. In many embodiments the polymers and sealants demonstrate reduced risk of spoilage that may be caused by low temperature storage of the polymer or uncured sealant. Compounds useful as stabilizing monomers include compounds according to formula I:CH&#x2550;CR&#x2014;CHR&#x2014;S&#x2014;R&#x2014;S&#x2014;CHR&#x2014;CR&#x2550;CH&#x2003;&#x2003;[I]wherein R, R, Rand Rare independently selected from &#x2014;H, &#x2014;CHor &#x2014;CH, andwherein Ris selected from divalent groups comprising 2-12 carbon atoms, 0-5 ether oxygen atoms and 0-5 thioether sulfur atoms, which may be straight, branched or cyclic.
