Synthesis and characterization of new hybrid microspheres with amide functionalization

Abstract

In this article, synthesis and characterization of new crosslinked hybrid microspheres are presented. This material was obtained by the emulsion-suspension polymerization of 1,4-divinylbenzene and trimethoxyvinylsilane. In the case of introducing biologically active functional groups on the surface of microspheres, methacrylamide as a third monomer was added. Chemical structures of all new materials were confirmed by the spectroscopic method (attenuated total reflectance-Fourier transform infrared spectroscopy) and elemental analysis. The influence of comonomer structure on the physico-chemical properties of the hybrid microspheres was investigated. Porous structures in a dry state were studied by means of nitrogen adsorption–desorption measurements. Thermal stabilities and degradation behavior of the obtained copolymers were characterized by the use of thermogravimetric/derivative thermo-gravimetric analysis.
