Solubility and diffusivity of methylmethacrylate and butylacrylate monomers in a MMA-BA copolymer
Mutual diffusion coefficients and sorption isotherms of methyl methacrylate (MMA) and butyl acrylate (BA) monomers in methyl methacrylate-butyl acrylate copolymer (MMA-BA) have been measured by gravimetric sorption. MMA ...
Solvent sorption in a polymer-solvent system - Importance of swelling and heat effects
Sorption experiments are often conducted in gravimetric sorption columns where several deviations from ideal conditions could potentially occur. For example, heat effects due to solvent sorption, errors introduced due to ...
Sorption and diffusion of water vapour on edible films
Two types of films consisting of sodium salt of carboxymethyl cellulose (NaCMC) and hydroxypropyl cellulose (HPC) as film forming materials and glycerin as plasticizer were prepared, characterized and their water vapour ...
Predicting emission characteristics of volatile organic compounds from wet surface coatings
A mathematical model is developed to describe the emission characteristics of VOCs from homogeneous wet coating materials deposited on impermeable substrates. The model considers mass transfer in the material and in air, ...
