    摘要: SUBSTITUTED AND UNSUBSTITUTED E-THIOCAPROLACTONES ARE READILY PREPARED IN A TWO STEP PROCESS. IN THE FIRST STEP AN E-CAPROLACTONE AND CARBON DISULFIDE OR CARBONYL SULFIDE ARE REACTED TO AN OLIGOMER PRODUCT, AND IN THE SECOND STEP THE OLIGOMER PRODUCT UNDERGOES A BASE CATALYZED REARRANGEMENT TO FORM THE E-THIOCAPROLACTONE.

    摘要: Thiolactones can be polymerized using as a catalyst, manganous or cadmium ions, in conjunction with an initiator such as water or an organic compound containing a primary hydroxyl or sulfhydryl group. They can also be copolymerized with lactones using the same catalyst/initiator system.
