A model graft copolymer material consisting of polystyrene (PS) chains grafted onto a poly ethyl acrylate) backbone was studied by small-angle neutron scattering (SANS) and neutron reflectivity.
The effects of particle size and polymer location (core or shell) on the mechanical properties of core/shell materials composed of polystyrene (PST) and poly(butyl acrylate) (PBA) made by a two-stage emulsion or microemulsion polymerization process are reported.
Two main types of material were assessed: Star Frost 76 × 26 mm white glass slides (G) (Knittel Glass, Germany), used as the reference material, and rectangular discs of polystyrene (PS) 76 × 26 mm (Paccor Packaging Poland, Skierniewice), a material certified by the Polish National Institute of Public Health and approved for contact with food.
A series of polystyrene materials was created with increasing oxygen surface incorporation and, concurrently, decreasing water-contact angles.
And later this month, passers-by will be delighted by a dramatic lighting installation in the Design Museum Tank - a miniature public exhibition space outside the museum - made out of that most humble of materials, polystyrene.
It's true: the most exciting element of Christmas used to be the "snow" beneath the tree, made of polystyrene packing material, which, I remember, thrillingly retained one's teeth marks when you bit in.
Flasks were irradiated from above with a vertical beam, 2.5 mm of polystyrene build up material was placed on top of the flasks and the surface of the build-up material was at a distance of 76 cm from the source.
The results from the mathematical model were validated by qualitative comparison with the experimental results of mechanical testing of polystyrene electrospun nanofibrous materials.
With the help of self organized opal structures of polystyrene spheres macroporous materials of Ag, Al and conducting polymers can be made.
These materials are composed of glassy domains of polystyrene, which physically link soft rubbery chain segments made of either polybutadiene or polyisoprene.
