Paper Title:
Reactive Compatibilization in Nano-Silica Filled Polypropylene Composites
  Abstract

Nano-sized silica was pre-grafted with poly(glycidyl methacrylate) (PGMA) by solution free-radical polymerization. When these grafted silica particles were melt compounded with polypropylene (PP), reactive compatibilization effect was perceived due to the chemical bonding between the PGMA and amine functionalized PP, which led to a significant increase of tensile strength and notch impact strength of PP at rather low filler content. Accordingly, compatibility of each kind of the functionalized PP with grafted SiO2 was evaluated through investigating the mechanical properties, crystallization behavior and rheological performance of the composites. The results show that the reactive compatibilization is capable of providing stronger interfacial adhesion.
