In this study, a new synthetic methodology for the functionalization of polystyrene (PS) has been developed, in which maleic anhydride was used in the presence of zinc oxide as catalyst and microwave ...

Although the use of an organically treated clay can improve the miscibility of the clay with the polymer matrix, the main limitation of such clay is lower thermal stability relative to the high ...

French energy company Total SA has completed an industrial scale test run incorporating about 20 percent of post-consumer recycled polystyrene within virgin polystyrene. The company announced June 19 ...

Traditional methods like gel permeation chromatography (GPC) use a single detector to compare polymer samples, and as a result they are not capable of providing comprehensive comparison results.

A new study conducted by researchers from the University of Delaware and Argonne National Laboratory describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known ...

It is important to closely monitor the amount of polybutadiene added, so that the flexibility of the polystyrene polymer may be regulated. This application note outlines how Nuclear Magnetic Resonance ...

Static light scattering (SLS) is a non-invasive technique used for characterizing macromolecules in solution. A beam of monochromatic light is directed through a sample and the intensity of the light ...

Figure 1 shows the calibration generated from these samples. The graph illustrates the calibration of the NMR signal against a value of polybutadiene content obtained by a standard technique. Figure 1 ...

This year marks the 90th anniversary of polystyrene, and while some have argued it’s time for this and other polymers to retire, others envision a greener future for the material. Polystyrene sprang ...
