| 中文摘要 | a facile method is employed to prepare a series of lldpe/pa6 blends with co-continuous morphology with low pa6 content via reactive extrusion. in these blends, co-continuous morphology is obtained by introducing graft copolymers with both high and low molecular weight trunk chains to the interface simultaneously. maleic anhydride functionalized polybutadine (pb-g-mah, (m) over bar (n) approximate to 3000g/mol and mah content = 10 wt%) is first melt grafted onto the lldpe backbones with dicumyl peroxide (dcp) as an initiator. part of pb-g-mah is grafted onto lldpe to form lldpe-g-pb-g-mah copolymer. during reactive extrusion, in-situ formed copolymer ii (polybutadiene-graft-polyamide, pb-g-pa6) with a low molecular weight trunk chain (pb) is obtained from the reaction between the maleic anhydride group of free or non-grafted pb-g-mah and the amino group on pa6 molecules; while copolymer i (lldpe-g-pb-g-pa6) is obtained via the reaction between the maleic anhydride group of the grafted pb-g-mah (i.e., lldpe-g-pb-g-mah) and the amino group of pa6. copolymer i with a high molecular weight trunk chain, lldpe, should strengthen the interface and favor stress transfer, enabling the deformation of pa6; and copolymer ii (pb-g-pa6) with a low molecular weight trunk chain, pb, facilitates the formation of a flat interface between lldpe and pa6, thus promoting an elongated pa6 phase. therefore, co-continuous morphology of lldpe/pa6 blend is successfully prepared with only 25 wt% pa6 by controlling suitable amounts of copolymers i and ii in the blend.
