摘要: The graft of maleic anhydride (MAH) onto isotactic polypropylene (iPP) initiated by dicumyl peroxide (DCP) at 190 °C was studied means the Monte Carlo method. ceiling temperature theory, i.e., no possibility for homopolymerization MAH to occur higher temperatures, used in this study. simulation results show that most monomers were grafted radical chain ends arising from β scission a lower concentration, whereas amount attached tertiary carbons much larger than concentration various DCP concentrations. This conclusion gives good interpretation disagreement on grafting sites along PP chain. Moreover, it found degree increased considerably up peak value; thereafter, decreased continuously with increasing concentration. shifted direction and became DCP...
