✦ Synopsis

The dilute solution behaviour of poly(monoethyl itaconate) (PMEI) has been studied in 2-ethoxyethanol, methanol, dimethylsulfoxide and water, at 298 K, by intrinsic viscosity and fight scattering measurements, and size exclusion chromatography (SEC). Weight-average molecular weight was determined in methanol. PMEI shows typical polyelectrolyte behaviour. The Kuhn-Mark-Houwink-Sakurada relationships were established in the media studied. The conformational parameters (a and Co) and the thermodynamic parameter (B) were calculated. The results are compared with previous studies of poly(monomethyl itaconate).
