Cyclic thionylphosphazenes 1 undergo thermal ring-opening Polymerizati
on (TROP) to yield poly(thionylphosphazenes) 2 with backbones of four
coordinate sulfur(VI), nitrogen, and phosphorus atoms. During TROP of
1, macrocycles with analogous skeletal compositions were also formed.
Isolation, characterization and thermolysis studies of these species a
re described.
