EFFECT OF ORGANOCLAY ON THE MECHANICAL PROPERTIES AND CRYSTALLIZATION BEHAVIORS OF INJECTION-MOLDED PP/ABS/MONTMORILLONITE NANOCOMPOSITES

摘要

The mechanical properties and crystallization behaviors of PP/acrylonitrile-butadiene-styrene/organic montmorillonite nanocomposites (PP/ABS/OMMT) were studied. It was shown that, compatilizer PP-g-MAH not only improved the compatibility of PP/ABS, but also promoted the dispersity of OMMT particles in continuous phase PP and dispersed phase ABS. In addition, PP was reinforced and toughened by both layered silicate OMMT nanoparticles and ABS. The blend weight ratio of PP/ABS/OMMT, which was 85/15/2 wt%, had a concerted effect on toughening. OMMT nanoparticles also increased crystallization temperature and crystallinity.
