Abstract

The preparation of hyperbranched poly(amine ester) (HPAE) grafted silica nanoparticles (HPAE-SN) from methyl acrylate (MA) and diethanol amine (DEA) was analyzed. HPAE-SN was separated from the non-grafted HPAE by several cycles of dispersion in methanol with ultrasonic vibrations for 30 min and precipitated by centrifugation at 10⁴ rpm for 30 min. It was shown that the 'grafting onto' procedure is simpler and the percentage of grafting (PG) obtained is satisfactory. The results show that the modification of silica nanoparticles with HPAE could improve its dispersibility in polar organic solvents.
