Diffusion of linear polystyrene into crosslinked polystyrene
Polymer, 1997Abstract The diffusion of linear polystyrene (PS) into its crosslinked counterpart was studied using both neutron reflectivity (NR) and forward recoil scattering (FRES). The penetrant molecular weights were monodisperse and ranged from 10 000 to 690 000 g mol −1 . The molecular weight between crosslinks was kept at 22 000 g mol −1 .

Biocidal polystyrene beads. IV. Functionalized methylated polystyrene
Journal of Applied Polymer Science, 2004AbstractCrosslinked chloromethylated polystyrene beads were reacted with hydantoin and imidazolidinone derivatives to produce functionalized beads which could be rendered biocidal upon reaction with free chlorine or bromine. The biocidal efficacies of the N‐chlorinated, and in one case, the N‐brominated polymeric beads against Staphylococcus aureus and

Photodegradation of polystyrene and polystyrene containing benzophenone
Polymer Photochemistry, 1983Abstract The photodegradation of polystyrene has been studied by electron spin resonance, infra-red absorption, viscosity and gel fraction measurements. Irradiations with light from a medium pressure mercury lamp to polystyrene film at 45°C in vacuum, gave rise to the polystyryl radical.

Vitronectin adsorption on polystyrene and oxidized polystyrene
Journal of Colloid and Interface Science, 1989Abstract The secondary structure of human plasma vitronectin (VN) contains considerable β and random structure as ascertained by infrared spectroscopy and circular dichroism. VN adsorption kinetics on polystyrene and oxidized polystyrene were monitored by Fourier transform infrared spectroscopy.
