DESCRIPTION:Prof. Dr. Alex Plajer\, Universität Bayreuth\n\nRing-Opening 
 Terpolymerisation of Elemental Sulfur Waste via Lithium Catalysis\n\nEleme
 ntal sulfur\, a waste product of the oil refinement process\, represents a
  promising raw material for the synthesis of degradable polymers. We show 
 that simple lithium alkoxides facilitate the polymerisation of elemental s
 ulfur S8 with industrially relevant propylene oxide (PO) and CS2 (a base c
 hemical sourced from waste S8 itself) to give poly(monothiocarbonate-alt-S
 x) in which x can be controlled by the amount of supplied sulfur. The in s
 itu generation of thiolate intermediates obtained by a rearrangement\, whi
 ch follows CS2 and PO incorporation\, allows to combine S8 and epoxides in
 to one polymer sequence that would otherwise not be possible.
