中文摘要	a novel path of preparing pp/o-mmt nanocomposites, which pay attention to the breaking up of mmt original agglomerates and dispersing of its primary particles, rather than the intercalation or exfoliation degree of o-mmt, was reported. the method of predispersing the o-mmt particles into a polar poly(vinyl alcohol) (pva) matrix and then melt blending the pre-treated pva/o-mmt hybrids with pp was studied. 3-isopropenyl-alpha,alpha-dimethylbenzene-isocyanate (tmi) was used as a modifier of pva to improve the compatibility between pva and pp matrix. pre-disperse o-mmt with tmi modified pva was proved to be an effective way to get a composite with fine o-mmt particles dispersion. but the method, which is pre-dispersing o-mmt with non modified pva and then using tmi to modify such pva/o-mmt hybrid, would largely reduce the reaction degree between tmi and pva because of the relatively lower reaction temperature. although the latter method also can obtain finer dispersion composites than that with using pp-g-mah as compatibilizer, the relatively higher degradation degree of pp matrix in this method will limit the use of this nanocomposite.
