Fire properties of styrenic polymer–clay nanocomposites based on an oligomerically-modified clay [PDF]
, 2006 An oligomerically-modified clay has been used to fabricate nanocomposites with styrenic polymers, such as polystyrene, high-impacted polystyrene, poly(styrene-co-acrylonitrile) and acrylonitrile–butadiene–styrene by melt blending. The clay dispersion was

Mechanical testing of polystyrene/polystyrene laser welds
Polymer Testing, 2013 Abstract Properties of polystyrene/polystyrene (PS/PS) diode laser (808 nm) welded lap-joints were evaluated. First, the reptation time of the selected PS was determined using plate/plate oscillatory rheometry. The reptation time was critically dependent on temperature, but as long the temperature was above 200 °C, the reptation time was less than 8 ...

A Self-Assembled Microlensing Rotational Probe [PDF]
, 1998 A technique to measure microscopic rotational motion is presented. When a small fluorescent polystyrene microsphere is attached to a larger polystyrene microsphere, the larger sphere acts as a lens for the smaller microsphere and provides an optical ...
