中文摘要 | the graft of maleic anhydride (mah) onto isotactic polypropylene (ipp) initiated by dicumyl peroxide (dcp) at 190 degreesc was studied by means of the monte carlo method. the ceiling temperature theory, i.e., no possibility for the homopolymerization of ma-h to occur at higher temperatures, was used in this study. the simulation results show that most mah monomers were grafted onto the radical chain ends arising from beta scission at a lower mah concentration, whereas the amount of mah monomers attached to the tertiary carbons was much larger than that grafted onto the radical chain ends at a higher mah concentration for various dcp concentrations. this conclusion gives a good interpretation for the disagreement on the grafting sites along a pp chain. moreover, it was found that the grafting degree increased considerably up to a peak value; thereafter, it decreased continuously with increasing ma-h concentration. the peak shifted in the lower mah concentration direction and became lower and lower with increasing dcp concentration. when the dcp concentration was below 0.1 wt %, the peak was hardly observed. those results are in good agreement with the experiments. |
