Abstract
New polymer composites were synthesized by a new approach: radical polymerization in an ultrasonic field of the vinyl acetate inside the silica pores. The systems were extensively characterized by different techniques: X-ray photoelectron spectroscopy (XPS), gel permeation chromatography (GPC), thermogravimetric analysis (TGA), derivative thermogravimetry (DTG), dynamic mechanical analysis (DMA), and scanning electron microscopy (SEM). The formation of hybrid materials was proved by XPS. The molecular weight of the entrapped polymer in the cavities of the inorganic structure was assessed by GPC. The thermal properties of the composites were determined by TGA/DTG and DMA.
