Cohesive energy densities of poly(di‐n‐alkyl itaconates)

Abstract

The solubility parameters of the first ten members of the homologous series of poly(di‐n‐alkyl itaconates) were determined from limiting viscosity numbers in various organic solvents, differing in structure, polarity and hydrogen bonding capacity. Numerical values from 9.58 to 8.10 (cal/cm3)1/2 were obtained independently from measurements in hydrocarbon and oxygen containing solvents, close to solubility parameters calculated from polymer densities and molar attraction constants. The values obtained reflects the increasing paraffinic character within the series and can be correlated to solubility parameters published in the literature for structurally similar poly(alkyl acrylates) and poly(alkyl methacrylates).
