Research on polymer physics discussed by H. Svajdlenkova and co-researchers
June 30th, 2009
"We present the dynamics of a series of three paramagnetic molecules of different volume, mass, and shape in amorphous glass-forming polymer poly(isobutylene) (PIB) as investigated by means of electron spin resonance (ESR) technique," scientists writing in the Journal of Polymer Science Part B - Polymer Physics report.
"The reorientation behavior of spin probes is related to the ortho-positronium (o-Ps) annihilation in PIB from positron annihilation lifetime spectroscopy (PALS) and the extracted free volume information," wrote H. Svajdlenkova and colleagues.
The researchers concluded: "It is also related to the dynamic data of PIB from broadband...
