In the synthesis process of nanometer-size PS particles
functional polyperoxides(PPX) was used as an inisurf.The chemical composition and the structure of nanometer-size PS particles wese studied carefully by differential scanning calorimetry
thin-layer chromatography
solubility measurement
infrared spectrum etc.It was found that the product is predominantly composed of PS-PPX crosslinked polymer with trace of un-reacted peroxo-groups on its chains.
