Conclusions
-
1.
Using a fractional extraction method, a macrocyclic trimer, cyclotris(m-phenylenesulfide), has been isolated from poly-m-phenylenesulfide and characterized.
-
2.
Conformational rigidity of molecules of cyclotris(m-phenylenesulfide), in the presence of an insubstantial degree of strain for the macrocycle, has been established by x-ray structural analysis. The relatively low yields of larger macrocycles in the polycondensation reaction can be attributed to a greater degree of strain in these molecules, i.e., to larger energies of formation.
