Poly(butyl acrylate) (PBA) was grafted onto nano SiO2 via atom transfer radical polymerization, and the effect of PBA grafted nano SiO2 (SiO2-g-PBA) particles on the stress-strain behavior and thermal stability of polyethylene terephthalate (PET) was studied. The results of Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), mechanical properties, Vicat softening temperature and thermogravimetric (TG) analysis show that SiO2-g-PBA composite particles are evenly dispersed in the PET matrix. When the mass content of SiO2-g-PBA composite particles is 2%, the tensile strength, tensile strain at break, tensile fracture energy and Vicat softening temperature of PET/SiO2-g-PBA composites are increased by 11.3%,23.1%,94.01% and 3.6 ℃ respectively in comparison with those of pure PET.
