Copolymers containing ODCA had somewhat higher acetone solubilities that PET, due mainly to the lower levels of crystallinity in the ODCA-containing polymers than in PET.doi:10.1016/S0376-7388(99)00151-9McDowell, C.CPartin, J.MFreeman, B.DMcNeely, G.WElsevier BVJournal of Membrane Science...
Polymer solubility and selective adsorption have been examined in the co-solvent system acetone (1), cyclohexanol (2), polystyrene (3) in which the solubility parameters for components (1) and (2) are both larger than the polymer (3). The selective adsorption parameter (λ∗) exhibits the...
The solubility of phenyl acetic acid, p-hydroxyphenylacetic acid, p-aminophenylacetic acid, p-hydroxybenzoic acid, and ibuprofen in water and in a range of organic solvents of relevance to industrial processing is reported. The solvents used are water, methanol, ethanol, 2-propanol, acetone, 4-...

HSP are useful in selecting process solvents, additives in formulations, for the blending of polymers, and for the control of kinetics and monomer-sequence distributions in co-polymers. HSP have been used as the basis for solvent selection models and computerized methods, but they can also be ...
Solutions of polymethyl methacrylate in the solvents ethanol and acetone were processed via SAS using compressed carbon dioxide. Also, copolymers from the monomers methyl methacrylate and vinyl pyrrolidone were processed using SAS to observe the effects of their solubility in ethanol. The solubilities of...

Solubility data of solids in liquids as well as gas solubility data in hyper-branched polymers [124] or adsorbents boiling at high temperatures can be obtained. Results from measurements of gas solubility data with a FIS-QCM are presented here for the first time. Solubility of solids in ...
PolymersPolyvinyl alkyl ester of carboxylic acids are a family of macromolecules in which the side chain esters (pendant groups) increase in molar mass and hydrophobicity and decrease in structural polarity as the number of carbons in the carboxylic acid increases. The most ...
