Foaming behavior of isotactic polypropylene in supercritical CO2 influenced by phase morphology via chain grafting
Polystyrene (PS) and poly(methyl methacrylate) (PMMA) grafted isotactic polypropylene copolymers (iPP-g-PS and iPP-g-PMMA) with well-defined chain structure were synthesized by atom transfer radical polymerization using a branched iPP (iPP-B) as polymerization precursor. The branched and grafted iPP
were foamed by using supercritical CO2 as the blowing agent with a batch method. Compared to...

Supercritical Carbon Dioxide Assisted Solid-State Grafting Process of Maleic Anhydride onto Polypropylene
The work reported in this paper aimed at exploring the advantages of using supercritical carbon
dioxide (scCO2) as an environmentally benign solvent and swelling agent for carrying out the
grafting process of maleic anhydride onto polypropylene in the solid state. The effects of scCO2
on the melting temperature and melting enthalpy of an isotactic polypropylene (iPP) were
investigated first in...
