| 中文摘要 | rare earth oxide, neodymium oxide (nd2o3), -assisted melt free-radical grafting of maleic anhydride (mah) on isotactic-polypropylene (i-pp) was carried out by reactive extrusion. the experimental results reveal that the addition of nd2o3 into reactive system leads to an enhancement of the grafting degree of mah, along with an elevated degradation of i-pp matrix. when nd2o3 content is 4.5 mmol %, the increment of the grafting degree of mah (maximally) is up to about 30% compared with that of the related system without adding nd2o3, while the severest degradation of i-pp matrix simultaneously occurs. on the basis of the reaction mechanism of pp-g-mah proposed before, the sequence of beta-scission and grafting reaction is discussed in detail. it is found that, for the reactive system studied, most tertiary macroradicals first undergo beta-scission, and then, grafting reaction with mah takes place at the new radical chain ends. the imported nd2o3 has no effect on the aforementioned reaction mechanism, whereas it enhances the initiating efficiency of the initiator, dicumyl peroxide (dcp). |
