Abstract
The self-diffusion coefficients of acetone (ACT), 2-butanone (MEK), 2-pentanone (MPK), 2-hexanone (MBK), 3-methyl-2-butanone (MiPK), 4-methyl-2-pentanone (MiBK), and 3,3-dimethyl-2-butanone (MtBK), mixed in various proportions with poly(methyl methacrylate) (PMMA; MW ca. 60 000) have been determined by the use of the pulsed-gradient spin-echo NMR technique. The self-diffusion coefficients of the neat solvents decrease in the order ACT>MEK>MPK>MiPK>MBK>MiBK>MtBK, according to both their increasing overall molecular length and geometric cross section
