Resumen
The dilute solution behavior of poly(methyl dodecyl itaconate) (PMeDoI) has been studied in THF and n-butanol at 298 K, by intrinsic viscosity, light scattering, and size-exclusion chromatography (SEC) measurements. The Kuhn-Mark-Houwink-Sakurada relationships were established. The flexibility factors sigma and C infinity and the thermodynamic parameters B were calculated using the Stockmayer-Fixman equation. The A2 and the B values are indicative of the presence of the excluded volume effect. The results obtained are compared with those previously found for poly(mono dodecyl itaconate) (PMDoI) and discussed in terms of specific influence of the free carboxylic group in the poly(monoester).
