Abstract

Vinyl polyperoxides constitute a narrow but important class of polymers because they show several novel physicochemical properties. Having a highly flexible backbone, they are also highly viscous amorphous materials. Interestingly, we found that poly( -phenyl styrene peroxide) (PAPSP) forms a crystalline structure that is perhaps the first crystalline structure known in the family of polyperoxides. From detailed powder X-ray diffraction analysis and simulation studies, PAPSP was found to have a helical conformation. Another interesting feature of PAPSP is that it is highly thermally stable and photostable compared to other known polyperoxides. This makes PAPSP the most eligible candidate for exploring novel application potentials.
