Diffusivity of small molecules in polymers : carboxylic acids in polystyrene
Gravimetry was used to study the diffusion of a homologous series of linear carboxylic acids (Cn, with n=2, 6-16) in amorphous polystyrene at temperatures from 35 ºC to 165 ºC, that is, both below and above the polymer glass transition temperature of 100 ºC. All the mass uptake results are well desc...
