Abstract

The synthesis and the dilute solutions properties of poly(1-indanyl methacrylate) (P1-IM) in THF and 1-4 dioxane at 298 K (?-solvent) were studied by viscosity, classical light scattering and size exclusion chromatography (SEC) measurements. The Kuhn-Mark-Houwink-Sakurada relationships were established in the solvents studied. The unperturbed dimensions were determined by using the Stockmayer-Fixman extrapolation. From these results, the rigidity parameter ? was determined. The results show that the rigidity of P1-IM is higher than that of poly(5-indanyl methacrylate). The influence of the nature of the spacer group methylene or cyclic group is discussed and also compared with previous results found for another aromatic poly(methacrylates) series.
