Crack formation in. divinyl benzene (DVB)-crosslinked polystyrene samples swollen by cyclohexane was followed as a function of time, temperature, degree of crosslinking and initial sample thickness. In the range of crosslinking ratios between 5.2 and 25.8 x 10 3 mol DVB/mol styrene, highly crosslink
The transport of a solute by diffusion into a glassy polymer can lead to swelling of the material. For certain types of polymers, a sharp interface is formed between the swollen region and the glassy core. When the density of the swollen material is much smaller than the density of the glass, a sign
