Solution properties of poly(thiocarbonates) containing cyclic side chains

Poly(thiocarbonates) with cyclic side chains have been studied in the theta solvent 1,4-dioxane. The Mark-Houwink-Sakurada (MHS) relationships were established and the uperturbed dimensions determined. The conformational parameters were compared with those of other poly(thiocarbonates) and related polymers. It was found that the polymers containing cyclic groups present a more extended and rigid chain. A marked influence of the nature and structure of the side chain on the conformational parameters was found.
