摘要

<正> The compatibility of PP/N-66 blending system modified with maleated polypropylene was studied by means of SEM

DMA and other mechanical testing. It was found that when proper amount of modifier was applied

the compatibility was greatly enhanced and the impact toughness was significantly improved. An important direct evidence of the formation of the interfacial copolymer was also found. However

when excessive amount of modifier was used

the modification effect was not conspicuous. The phenomena were interpreted from a view of molecular motion that the interfacial block copolymer forced the two components to ’compatibilize’ and many flexible PP molecules were set free from the restraint of the crystallites of plain PP so as to absorb much more impact energy.
