Novel Block Copolymers as Compatibilizers for Nanocomposites

摘要

A series of compatibilizers for polypropylene/montmorillonite nanocomposites are synthesized based con reactive block copolymers made by controlled radical polymerization (CRP). The effect of intrinsic variables of the compatibilizer such as: graft density, molecular weight of the graft, polarity and composition of the polyolefin backbone are fully explored and trends on the dispersion of the organoclay are correlated with mechanical properties of the nanocomposites.
