Plasma modification of polypropylene surfaces and grafting copolymerization of styrene onto polypropylene
Chinese Journal of Polymer Science 30, #3 (2012)
Ma et al, China, modified the surface of polypropylene (iPP) with glow discharge plasma of Ar, so that the modified surfaces of iPP films are obtained.  The surfaces of iPP are achieved with Ar plasma treatment followed by grafting copolymerization with styrene (St) in St.  The grafting rate is dependent on plasma exposure time and discharge voltage. The studies show that homopolymerization of St occurs at the same time during the grafting copolymerization of St onto iPP.  (RDC 4/30/2012)

The application of response surface methodology on the synthesis of grafted polypropylene through the solvothermal rout
(pages 109–117)
Advances in Polymer Technology 31 #2 (2012)
Zheng et al of Fuzhou University, China, used xylene–water-thermal reaction of polypropylene (PP), styrene (St), and maleic anhydride (MAH) under pressure to prepare grafting polymers. Infrared (IR) spectra and NMR spectra confirmed that MAH and St were successfully grafted onto the PP backbones. Through differential scanning calorimetry (DSC) and X-ray analysis, it was found that the crystallinity of grafting polymers decreased due to the formation of side chains.  (RDC 4/24/2012)
